Background: Periorificial dermatitis (POD) is a common inflammatory skin condition primarily affecting infants, children, and young women. Novel therapies such as phosphodiesterase 4 (PDE4) inhibitors provide promising non-steroidal anti-inflammatory treatment options. Objective: This study evaluated the efficacy and safety of topical crisaborole 2% ointment, a PDE4 inhibitor, for treating pediatric patients with POD. Methods: A randomized, double-blind, vehicle-controlled trial included 23 participants aged 3 months to 18 years. Patients were treated with crisaborole 2% ointment or placebo for 4 weeks, followed by a 4-week treatment-free observational period. Primary endpoints were a 50% reduction in the Perioral Dermatitis Severity Index (PODSI) and an Investigator’s Global Assessment (IGA) score of 0 or 1 by day 14. Assessments were also conducted on days 29 and 58. Secondary measures included changes in Quality-of-Life Index scores over time and safety evaluations. Results: Both groups demonstrated improvement in PODSI and IGA scores during treatment.Although a small, non-significant numerical trend favored the crisaborole group across primary and secondary endpoints, no statistically significant differences between crisaborole and placebo were observed at any time point. Mild burning or stinging were reported more frequently in the crisaborole group, but they were generally tolerable. Conclusion While there was a modest numerical trend favoring crisaborole, its efficacy was not statistically superior to placebo in this small pilot study. Larger studies are needed to further validate the efficacy of crisaborole for the treatment for POD.

Objective: Cisplatin, a widely used chemotherapy agent, is known to induce testopathy and degeneration of the germinal epithelium (GE). Origanum vulgare L. (OV) leaf extract, due to its antioxidative properties, may alleviate such cellular damage. This experimental study was conducted to evaluate the protective and therapeutic effects of OV against cisplatin-induced testopathy. Methods: Forty-eight male Naval Medical Research Institute mice were assigned to six groups. Testopathy was induced via intraperitoneal injection of cisplatin (single dose, 1 mg/kg on day 0). OV was administered as treatment (400 mg/kg orally, 5 days per week, for 5 weeks). Phytochemical screening of OV was also performed. After the experimental period, the animals were euthanized, and both blood serum and testicular samples were collected. Total body weight and total testicular weight were measured. Histopathological examination using hematoxylin and eosin staining (to assess the gonadosomatic index [GSI]) and immunohistochemical (IHC) detection of 3β-hydroxysteroid dehydrogenase (3β-HSD) protein were conducted. Expression levels of the p53 and B-cell lymphoma 2 (Bcl-2) genes, as well as serum testosterone levels, were evaluated. Statistical analysis was performed with SPSS ver.16, and significance was set at p<0.05. Results: A phytochemical analysis of OV confirmed the presence of antioxidant compounds. Cisplatin administration resulted in significant detrimental alterations in testicular tissue (p<0.05). In animals receiving OV following cisplatin exposure, the GSI, testosterone levels, histological parameters, and total testicular weight improved toward physiological values (p<0.05). Additionally, IHC staining for 3β-HSD protein indicated regeneration of Leydig cells. Gene expression analysis showed down-regulation of p53 and up-regulation of Bcl-2 (p<0.05). Conclusion OV administration, owing to its antioxidative characteristics, shows promise as a protective phytomedicine against cisplatin-induced testopathy. OV promotes GE proliferation, enhances testosterone secretion, and modulates the expression of apoptotic genes.

Introduction: Histoplasmosis is a rare opportunistic, inhalation-acquired systemic mycosis caused by Histoplasma capsulatum, endemic to Southeast Asia, including Malaysia. Although classically seen in immunocompromised hosts, it is increasingly reported in immunocompetent individuals. Infection is associated with environmental exposures such as bat or bird droppings and soil disruption. Histoplasmosis is a progressive granulomatous disease that can closely mimic tuberculosis and malignancy, making diagnosis challenging. Case: An 87-year-old Malay male with a history of treated pulmonary tuberculosis presented with a 6-month history of intermittent fever, anorexia, weight loss, and hypotension. Initial computed tomography imaging demonstrated bilateral heterogeneous adrenal masses (right: 2.2 × 3.7 × 5.0 cm; left: 2.0 × 3.7 × 5.2 cm) with indeterminate washout characteristics. Biochemical adrenal evaluation, including a short Synacthen test, confirmed primary adrenal insufficiency. Extensive microbiological and malignancy workup, including bronchoscopy, cultures, and tumor markers, was non-diagnostic. In view of clinical deterioration and epidemiological risk, empirical antituberculous therapy was initiated; however, no clinical improvement was observed after 2 months. PET-FDG revealed intensely hypermetabolic bilateral adrenal masses (SUVmax right 16.7, left 13.2) with no other abnormal foci. Non-invasive fungal investigations were negative. Definitive diagnosis was established via computed tomography-guided adrenal biopsy, which demonstrated necrotizing granulomatous inflammation with intracellular yeasts, subsequently identified as H. capsulatum. The patient was treated with oral itraconazole and corticosteroid replacement, resulting in significant clinical improvement and planned interval radiological reassessment. Conclusion Disseminated histoplasmosis is a diagnostic challenge, particularly in frail elderly patients, where invasive procedures may be delayed. It can mimic tuberculosis and malignancy and may lack an identifiable exposure history. Non-invasive tests may be inconclusive, making tissue biopsy essential. Adrenal involvement may result in primary adrenal insufficiency, further complicating the clinical picture. Early consideration and timely confirmation are crucial for appropriate management.

Introduction: Improving glycemic control while minimizing unnecessary insulin exposure is an important goal in diabetes management. The Rapid Optimization Clinic (ROC) was established as a structured multidisciplinary service to support therapy individualization, close follow-up, and timely insulin deintensification. This audit evaluated early changes in glycated hemoglobin A1c (HbA1c) and insulin treatment burden following ROC care over 3 months. Methodology: We conducted a retrospective audit of routine clinical data from patients with diabetes managed in the ROC at a district hospital. Baseline and 3-month HbA1c and insulin data were extracted from non-electronic clinic records. Insulin dose was standardized as total daily dose (TDD) in units/kg/day. Insulin deintensification was evaluated primarily by change in TDD from baseline to 3 months and by the proportion of patients who discontinued insulin during follow-up. Paired analyses were performed for patients with complete baseline and follow-up data for each outcome. Continuous variables are presented as mean ± standard deviation or median with interquartile range, as appropriate. Exploratory analyses were undertaken to assess whether available patient factors were associated with HbA1c improvement. Results: Twenty-three patients were included. Paired HbA1c data were available for 12 patients, whereas paired TDD data were available for 21 patients. Mean HbA1c decreased from 10.78 ± 2.59% at baseline to 8.42 ± 2.29% at 3 months, representing a mean reduction of 2.36 percentage points (95% confidence interval [CI] 0.09–4.62; p = 0.043). Mean TDD decreased from 0.434 ± 0.248 to 0.286 ± 0.313 units/kg/day, corresponding to a mean reduction of 0.148 units/kg/day (95% CI 0.077–0.219; p <0.001). Insulin was discontinued in 9 of 21 patients (42.9%). No clear association was observed between HbA1c improvement and age, sex, or number of visits. Interpretation is limited by the small sample size, reflecting the early phase of a newly established clinic. Conclusion In this early audit, ROC care was associated with clinically meaningful improvement in glycemic control and significant insulin deintensification over 3 months. These findings support the potential role of a structured multidisciplinary optimization clinic in delivering individualized diabetes care and facilitating safe reduction of insulin burden.

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.

Introduction: Isolated hypothyroxinemia (IH) in pregnancy, characterized by low free thyroxine 4 (FT4) with normal thyroidstimulating hormone (TSH), has a reported prevalence of 1.3–8%. We present a diagnostically challenging case that initially mimicked central hypothyroidism before evolving into classic IH. Case: A 37-year-old G4P3 female at 22 + 3 weeks gestation with β-thalassemia trait presented with palpitations and tachycardia (150–184 bpm). A bedside echocardiogram showed volume depletion. Her heart rate improved to 108– 116 bpm following a 1.5 L normal saline bolus. Incidentally, thyroid function tests (TFTs) revealed both low FT4 6.04 pmol/L (7.86–14.41) and low TSH 0.009 mIU/L (0.38–5.33). Anti-thyroid peroxidase antibody was markedly elevated at 360 IU/mL (<35). At 24 + 4 weeks, TFTs showed persistently low FT4 (5.84 pmol/L) and TSH (0.022 mIU/L). Differential diagnoses included central hypothyroidism or assay interference. Tests were repeated using different platforms. Both the Beckman system (FT4: 5.73 pmol/L, TSH: 0.086 mIU/L) and Roche system (FT4: 8.83 pmol/L [12.0–22.0], TSH: 0.11 mIU/L [0.27–4.20]) confirmed low values, ruling out assay interference. Following endocrinology consultation and given her asymptomatic status, IH was considered most likely, and a plan for close monitoring was initiated. Serial follow-up demonstrated biochemical evolution. By 31 + 6 weeks, TFTs showed a low TSH (0.753 mIU/L) with an FT4 level (5.86 pmol/L) within the normal reference range, a pattern typical of IH in pregnancy. Repeat TFTs 6 weeks postpartum showed both TSH and FT4 within normal range. Conclusion This case illustrates a rare and unexpected biochemical progression of IH in pregnancy, initially presenting with a pattern indistinguishable from central hypothyroidism. It underscores that in an asymptomatic, fertile patient, IH can manifest with an atypical pattern early in gestation. The findings suggest that vigilant serial monitoring, rather than immediate extensive pituitary workup, may be a prudent initial approach in such scenarios, as the biochemical profile can normalize toward the classic IH pattern as pregnancy advances.

The administration of botulinum toxin A (BTA) into the gastric wall has emerged as a novel endoscopic bariatric procedure. Although over 20 years have elapsed since the initial human trial of intragastric BTA injection, considerable debate remains surrounding the safety, efficacy, and procedural instructions of this approach. The current literature exhibits discrepancies in the methodologies employed across studies, including differences in the dosage of BTA administered, injection site, number and depth of injections, post-procedural dietary modifications, and follow-up duration. This study reviewed the state-of-the-art use of BTA for weight loss and focused on the clinical evidence of the therapeutic applications of BTA for obesity. Studies with consistent outcome measures and methodologies are necessary to thoroughly assess the potential effects of BTA on weight management.

Objective: Treating wide-necked bifurcation aneurysms (WNBA) is challenging. Nevertheless, recent progress in endovascular techniques is promising. Woven EndoBridge devices (WEB) have exhibited outcomes comparable to conventional treatments like stent-assisted coiling (SAC) in treating aneurysms. However, their safety and efficacy in managing acutely ruptured aneurysms remain a topic of interest. This study focuses on this issue. Methods: We searched our database from 2020 to 2023 and found 38 patients with acutely (< a week) ruptured WNBA. We extracted radiologic and clinical data from the available medical reports. Favorable functional and radiologic outcomes were assessed using the modified Rankin scale (mRS) and modified Raymond–Roy occlusion classification (MRRC). Results: Our study population comprised 15 aneurysms treated with WEB and 25 treated with SAC. Operational time was significantly lower in the WEB compared to the SAC group (39.3 vs 66.2 minutes, p value: < 0.001). Immediate (p value=0.64) and the 18th-month (p value=0.42) occlusion rates were comparable between the two groups. Favorable mRS scores in the 3rd month were seen in 100% of SAC patients and 93.3% of WEB patients (p value=0.79). Retreatment (p value=1.0) and complication (p value=0.39) rates were comparable. Vasospasms after the procedure were the most common complication. Conclusions WEB demonstrated comparable safety and efficacy to SAC in patients with acutely ruptured WNBA. Notably, WEB had a shorter procedure duration. Additional studies with extended follow-up periods are necessary for comprehensive evaluation.

Background: Fine needle aspiration (FNA) is a widely utilized technique for assessing thyroid nodules; however, its inherent non-diagnostic rate poses diagnostic challenges. The present study aimed to evaluate and compare the diagnostic efficacy of FNA, core needle biopsy (CNB), and their combined application in the assessment of thyroid nodules. Methods: A total of 56 nodules from 50 patients was analyzed using both FNA and simultaneous CNB. The ultrasound characteristics were categorized according to the American College of Radiology Thyroid Imaging Reporting and Data Systems classification system. The study compared the sensitivity, specificity, and accuracy of FNA, CNB, and the combination of the two techniques. Results: The concordance between FNA and CNB was notably high, with a kappa coefficient of 0.837. The sensitivity for detecting thyroid malignancy was found to be 25.0% for FNA, 66.7% for CNB, and 83.3% for the combined FNA/CNB approach, with corresponding specificities of 84.6%, 97.4%, and 97.4%. The accuracy of the FNA/CNB combination was the highest at 94.1%. Conclusions The findings of this study indicate that both CNB and the FNA/CNB combination offer greater diagnostic accuracy for thyroid malignancy compared to FNA alone, with no significant complications reported. Integrating CNB with FNA findings may enhance management strategies and treatment outcomes for patients with thyroid nodules.
