Introduction: Diabetic ketoacidosis (DKA) is a life-threatening complication associated with significant morbidity and healthcare burden. Despite advances in diabetes care, recurrent DKA remains common, often reflecting gaps in treatment adherence and patient education. Identifying predictors of recurrence is crucial for risk stratification and targeted intervention. Methodology: We conducted a retrospective observational study of all adult DKA admissions to a tertiary centre between 2001 and 2025. Electronic medical records were reviewed for demographic data, biochemical parameters, precipitating factors, and clinical outcomes. DKA was defined using standard biochemical criteria. Recurrent DKA was defined as ≥2 admissions during the study period. Factors associated with recurrent DKA admissions were analyzed. Patients under the age of 18 years and those with missing vital information were excluded. Results: A total of 667 DKA admissions, comprising 566 patients, were identified, of which 101 admissions (15.1%) were recurrent, involving 65 patients. Among recurrent DKA episodes, the most common precipitating factors were infection (64.4%) and insulin omission (62.4%). After multivariate analyses, patients with type 1 diabetes mellitus (T1DM) were more likely to develop recurrent DKA compared to those with type 2 diabetes mellitus (aOR 4.16; 95% confidence interval [CI] 2.58–6.70; p <0.001). Insulin omission was strongly associated with recurrent DKA (aOR 2.29; 95% CI 1.46–3.60; p <0.001). In contrast, baseline glycated hemoglobin and chronic kidney disease were not significantly associated with recurrence. Diabetic counseling during the first DKA admission did not reduce recurrent DKA. There were no significant differences in mortality (3.9% vs 6.2%, p = 0.524) or critical care admission rates (40.6% vs 38.7%, p = 0.718) between recurrent and first DKA episodes. Conclusion Recurrent DKA accounts for a substantial proportion of DKA admissions and is strongly associated with insulin omission and T1DM. Our findings suggest that recurrent DKA is driven predominantly by behavioral and adherencerelated factors, indicating the need for multidisciplinary interventions beyond standard inpatient counseling.
Diabetic Ketoacidosis ; Retrospective Studies

Introduction: The rising incidence of diabetic ketoacidosis (DKA) in type 2 diabetes mellitus (T2DM) represents a paradigm shift from its traditional recognition as a hallmark complication of type 1 diabetes mellitus (T1DM). However, contemporary data comparing clinical presentation, precipitating factors, and outcomes between these two populations remain limited. Methodology: In this retrospective observational study, all adult DKA admissions with T1DM or T2DM at a tertiary centre between 2001 and 2025 were studied. DKA was defined according to standard biochemical criteria. Electronic medical records were reviewed to extract demographic data, biochemical parameters, precipitating factors, management details, and clinical outcomes of all adult DKA admission in T1DM and T2DM. Patients aged <18 years or those with incomplete data were excluded. Results: A total of 601 DKA episodes were analyzed, comprising 130 (21.6%) in patients with T1DM and 471 (78.4%) in those with T2DM. Mean age was 26.9 ± 0.71 years for T1DM and 52.1 ± 0.7 years for T2DM. Gender distribution was balanced (male 48.3%, female 51.7%). Mean hemoglobin A1c (HbA1c) was 11.3 ± 0.3% in T1DM and 12.1 ± 0.2% in T2DM. Infection was the most common precipitating factor overall (69.0%), occurring more frequently in T2DM than in T1DM (74.7% vs. 56.2%), followed by medication non-adherence (62.4% vs. 43.8%). Significant differences were observed between groups in admission pH, bicarbonate (both p <0.001), blood ketones (p = 0.028), and HbA1c (p = 0.010), whereas anion gap (p = 0.056) and blood glucose levels (p = 0.755) did not differ significantly. Clinical outcomes were comparable with respect to intensive care unit (ICU) admission rates (40.0% in T1DM vs. 39.0% in T2DM, p = 0.779) and median resolution time (p = 0.462). However, the median length of hospital stay was significantly longer in T2DM (8.2 ± 0.32 vs. 5.4 ± 0.4 days; p <0.001). Overall mortality was 6.0%, with substantially higher mortality in T2DM compared to T1DM (7.4% vs. 0.8%, p = 0.013). Conclusion In this large regional series of adult DKA, most episodes occurred in T2DM. Despite similar ICU admission rates and time to resolution, T2DM was associated with more frequent infection-related precipitants, longer hospital stays, and higher mortality, underscoring the need for targeted preventive strategies in this population.

Introduction: Diabetic ketoacidosis (DKA) in pregnancy is an uncommon yet life-threatening emergency, with disproportionate risks to both mother and fetus. Pregnancy-specific physiological changes predispose patients to rapid metabolic decompensation, often with atypical presentations. Despite this, local data remain limited. We describe the clinical profile, precipitating factors, and outcomes of DKA in pregnancy in a tertiary centre, with emphasis on potentially preventable triggers. Cases: Nine pregnant patients with DKA were identified from a retrospective review of all cases admitted for DKA from 2002 to 2025. Mean age was 31.67 ± 5.20 years; all were Malay. The majority had type 2 diabetes mellitus (55.6%), followed by type 1 diabetes (33.3%) and latent autoimmune diabetes in adults (11.1%). The mean period of amenorrhea was 19.67 ± 12.62 weeks. Infection was the leading precipitant (44.4%), with additional triggers including insulin omission (22.2%), hyperemesis gravidarum, preterm labor, steroid exposure, and perioperative fasting. Most diagnoses were made in the emergency department (55.6%). Biochemical parameters reflected significant severity (mean bicarbonate 7.89 ± 2.98 mmol/L; anion gap 25.00 ± 5.81), with 88.9% classified as severe DKA. Intensive Care Unit (ICU) care was required in 77.8% of cases. The majority (77.8%) were admitted to the ICU unit, with a median time to resolution of 13.00 ± 12.00 hours (interquartile range [IQR]), and the median hospital length of stay was 7.00 ± 5.00 days (IQR). Complications during treatment included hypokalemia (33.3%), acute kidney injury (22.2%), and hypoglycemia (11.1%). Rebound DKA occurred in one-third of patients. All patients were discharged clinically stable. Outcome data demonstrated pregnancy loss in three cases and one preterm birth. Conclusion DKA in pregnancy remains a severe and resource-intensive condition. This series highlights missed opportunities in prevention, with modifiable precipitants such as infection and insulin omission commonly identified. The high severity at presentation suggests delays in recognition. Early detection, optimized metabolic care, and targeted preventive strategies are crucial to improving maternal and fetal outcomes.

Introduction: Paragangliomas are rare neuroendocrine tumors arising from extra-adrenal chromaffin cells, with an estimated incidence of 2–8 cases per million per year. These tumors originate from neural crest–derived cells of the sympathetic and parasympathetic paraganglia and may secrete catecholamines, resulting in malignant hypertension or symptoms such as headache, palpitations, and diaphoresis. They can occur anywhere along the paravertebral and para-aortic regions from the skull base to the pelvic floor. Case: We report a case of a 14-year-old male with no known premorbid conditions who presented with presyncope and a 1-month history of headache. On examination, he had severe hypertension (242/167 mmHg), tachycardia (127 bpm), and grade IV hypertensive retinopathy. Investigations showed preserved renal function with markedly elevated 24-hour urinary metanephrines (normetanephrine 90.75 µmol/L). Computed tomography revealed a lobulated, heterogeneously enhancing mass measuring 5.0 × 6.1 × 5.4 cm along the left margin of the abdominal aorta at the infrarenal level, suggestive of an extra-adrenal lesion. Gallium-68 PET scan demonstrated a somatostatin receptor–avid left peritoneal mass. The patient underwent exploratory laparotomy and tumor excision, complicated intraoperatively by blood pressure lability requiring nitroprusside and inotropic support. Postoperatively, he improved significantly and was able to wean off all antihypertensive medications. Histopathology confirmed left retroperitoneal paraganglioma. Conclusion Primary peritoneal paraganglioma is a rare but important cause of secondary hypertension, especially in young patients presenting with hypertensive emergency. High index of suspicion is essential for early diagnosis. Management requires a multidisciplinary approach with careful preoperative optimization to minimize perioperative complications. Surgical resection remains the definitive treatment and, as demonstrated in this case, can result in marked clinical improvement with resolution of hypertension.

A series of comprehensive focus group discussions with active firefighters revealed that inconsistencies in incorporating a rigorous physical training program during work hours contributed significantly to the challenges of maintaining functional fitness, particularly strength. This article outlines a process for identifying the specific exercises required to enhance strength, drawing on the expertise and experience of physical trainers. Modified nominal group technique (mNGT) sessions were conducted to identify and rank exercises for five functional strengths (i.e., pushing, pulling, lifting, carrying, and dragging). A total of six physical trainers from the firefighter academy were interviewed to 1) identify the skeletal muscles involved in the functional movements using a visual aid; 2) generate ideas for exercises via brainstorming; 3) privately rank the displayed list of exercises for each muscle group involved in each functional movement; and 4) design a physical training programme for beginner, intermediate and advanced levels by manipulating loads. Males dominated the expert group (66.7%) and had a mean of 11.50 (SD 5.20) years of experience in physical training. The mNGTs yielded three top-ranking exercises for each functional strength: 1) Pushing: the push-up, sit-up, and jumping jack; 2) pulling: the push-up, jumping jack, and sit-up; 3) lifting: the jumping jack, push-up, and jumping squat; 4) carrying: the push-up, plank, and sit -up; and 5) dragging: the jumping jack, sit-up, and jumping squat. Then each exercise was designed for the beginner, intermediate, and advanced levels by manipulating loads (i.e. additional weight or number of repetitions). This study demonstrated that mNGT is an effective tool for identifying the three top-ranking exercises that address firefighter recruits’ functional strength. The experts chose multi-joint exercises targeting agonist and antagonist skeletal muscle groups and mimicking movements of daily work life. The exercises, corroborated by previous empirical evidence, provide opportunities for common skeletal muscle groupings to be targeted simultaneously to increase cardiovascular adaptations over a shorter period. The physical exercise is now ready to be implemented for piloting purposes among firefighter recruits.

The orbital tubercle, also known as Whitnall’s tubercle, was first described by S.E. Whitnall in 1911 and is a significant anatomical landmark on the zygomatic bone that serves various structural and clinical functions. Understanding its anatomy is essential for protecting adjacent soft tissues during surgical procedures and its role in forensic studies. This study aims to assess the prevalence, precise location, and morphological characteristics of Whitnall’s tubercle in adult human skulls. A cross-sectional observational study was conducted on 108 orbital fossae of 54 well-preserved adult human skulls.Whitnall’s tubercle was classified as apparent if visible or non-apparent if detectable only by palpation. Its dimensions and distances from nearby anatomical landmarks were measured. Statistical analyses were performed to compare measurements between sides. Whitnall’s tubercle was present in 106 (98.1%) out of 108 examined orbital fossae, with 67 classified as apparent and 39 as non-apparent. The mean longitudinal length was 6.59±0.99 mm on the right and 6.86±1.30 mm on the left (P=0.025), while the transverse lengths showed no significant difference (P=0.63). The majority of Whitnall’s tubercle presented an oval shape (92.5%), with no significant difference between sides (P=0.63). The distances between Whitnall’s tubercle and selected anatomical landmarks showed minor variations, but none reached statistical significance. This study provides valuable insights into the anatomical characteristics of Whitnall’s tubercle, emphasizing its clinical relevance in orbital surgery and forensic applications. Understanding these features can enhance surgical precision and improve patient outcomes.

ANTIBIOTICS FOR PAEDIATRIC PATIENTS IN DENTISTRY: AN OVERVIEW OF AVAILABLE GUIDELINES The administration of antibiotics in children undergoing dental procedures is generally contemplated in specific instances to prevent or address potential infections. This thorough review aims to enhance current guidelines by integrating additional evidence regarding the need for administering antibiotics to children undergoing dental treatments. We conducted an extensive review of literature, focusing solely on English-language sources retrieved from SCOPUS, MEDLINE, and PubMed databases up to August 2023. Our primary focus was on exploring the utilisation of antibiotics in paediatric dental care. Inaccurate antibiotic prescriptions can result in widespread consequences, such as the development of bacterial resistance, complications in the gastrointestinal and haematological systems, and disruptions in the bacterial microbiota. This review highlights the importance of following existing guidelines for prescribing antibiotics in paediatric dental care, underscoring the crucial role of dentists' clinical judgement before authorising prescriptions. Additionally, it strongly promotes collaborative communication with medical practitioners to evaluate the patient's clinical condition. Consequently, it is imperative to establish comprehensive antibiotic prescribing guidelines for dental professionals.

Medication review is an intervention with the potential to reduce drug-related problems (DRPs) in the elderly. This study aimed to determine the effect of pharmacists’ medication reviews on geriatric patients. This study accessed two online databases, MEDLINE Complete and Scopus, and examined all studies published in English between 2019 and 2023, except for reviews. The studies included (1) participants over 65 years of age and (2) medication reviews conducted by pharmacists. The titles, abstracts, and full texts were reviewed for data extraction to determine whether the studies satisfied the inclusion and exclusion criteria. Forty-four of the initial 709 articles were included in this study. The articles included discussions on the incidence rates of DRPs and potentially inappropriate medications (PIMs) (n=21), hospitalization (n=14), medication adherence (n=9), quality of life (QoL) (n=8), and falls (n=7). Pharmacist medication reviews were associated with a reduced incidence of DRPs and PIMs, and improved adherence to medications. Patients’ overall QoL is also increasing. However, pharmacist medication reviews were not strongly associated with decreased hospitalization or falls. A pharmacist’s medication review may be a feasible intervention for reducing the incidence rates of DRPs and PIMs, regardless of whether it is performed as a sole intervention or supplemented with other interventions. The intervention was also effective in increasing medication adherence and QoL.
