Background: Fibroblast activation protein inhibitor (FAPI) positron emission tomography (PET) has emerged as a promising modality for imaging the tumor microenvironment, specifically targeting cancer-associated fibroblasts (CAFs). While 18F-FDG targets glucose metabolism, 68Ga-FAPI targets stromal activation. Discrepancies between these modalities can offer unique insights into early pathogenesis. We report a rare case of incidental focal pancreatic uptake on 68Ga-FAPI PET/CT in a patient with prostate cancer, occurring in the absence of metabolic activity on 18F-FDG PET/CT or anatomical abnormalities on contrast-enhanced CT. Case presentation: A 75-year-old male with a history of acinar adenocarcinoma of the prostate (Gleason 7, post-TURP) underwent multimodal staging to evaluate for metastasis. 68Ga-PSMA PET/CT showed intermediate uptake in the prostate but no distant metastasis. Subsequent 68Ga-FAPI-04 PET/CT revealed a striking, intense focal uptake in the pancreatic body. Conversely, follow-up 18F-FDG PET/CT demonstrated physiological background uptake in the pancreas, and abdominal CT showed no pancreatic mass. Laboratory results indicated a slightly elevated CA 19-9 (45.6 U/mL). The findings present a diagnostic dilemma between early stromal-rich malignancy and focal inflammatory processes. Conclusion: This case highlights the FAPI-FDG Mismatch, suggesting that stromal remodeling may precede metabolic reprogramming and morphological changes in pancreatic lesions. 68Ga-FAPI PET/CT demonstrates superior sensitivity for detecting occult stromal activity, necessitating new diagnostic algorithms for incidentalomas in the era of stromal imaging.

Background: Cardiovascular disease remains the primary cause of mortality in patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD). Conventional risk factors fail to fully explain the high prevalence of resistant hypertension and intradialytic hemodynamic instability in this population. Emerging evidence points to the degradation of the endothelial glycocalyx (eGC), a protective luminal layer regulating vascular tone and permeability. Syndecan-1 (SDC-1), a core component of the eGC, sheds into the circulation during vascular stress. This study aimed to synthesize evidence regarding the magnitude of dialysis-induced SDC-1 shedding and its validity as a prognostic biomarker for survival and vascular stiffness. M ethods: We conducted a systematic review and associative meta-analysis of observational studies and clinical trials. We searched Scopus, PubMed, and Web of Science for studies quantifying serum SDC-1 in HD patients and relevant physiologic comparators. Data were stratified to analyze three domains: the second hit phenomenon (acute pre- vs. post-dialysis shedding), diagnostic correlations with pulse wave velocity (PWV) and fluid status, and prognostic hazard ratios (HR) for all-cause mortality. A random-effects model was employed to account for population heterogeneity, specifically stratifying hemodialysis cohorts from heart failure comparators. Results: Ten pivotal studies involving over 1,500 patients were included. The analysis confirmed a substantial acute surge in serum SDC-1 post-hemodialysis (Standardized Mean Difference = 1.24, p < 0.001), indicating that the dialysis procedure actively injures the endothelium. Elevated baseline SDC-1 correlated significantly with arterial stiffness (PWV) and sodium overload, supporting a mechanism of salt-induced vascular stiffening. In prognostic analysis, high SDC-1 was a robust independent predictor of mortality (Pooled HR = 1.65, 95% CI: 1.12–2.43). Conclusion: Hemodialysis acts as a vascular stressor, triggering acute shedding of the endothelial glycocalyx. This shedding is mechanistically linked to sodium dysregulation and vascular stiffness, independent of traditional uremic toxins. SDC-1 serves as a valuable prognostic marker for endothelial health and survival, suggesting a need for endothelium-protective dialysis strategies.

Background: Lipomeningomyelocele represents a complex spectrum of closed spinal dysraphism where surgical repair is frequently complicated by cerebrospinal fluid leakage. While overt fistulas are clinically apparent, occult or intermittent leaks in the pediatric population pose a severe diagnostic challenge. Magnetic resonance imaging, despite being the anatomical gold standard, frequently fails to distinguish active extravasation from postoperative seroma or edema due to overlapping signal intensities. This study evaluates the diagnostic superiority of Tc-99m DTPA Hybrid SPECT/CT cisternography in resolving this dilemma. Case presentation: A 5-month-old female underwent resection of a large lumbosacral lipomeningomyelocele. Postoperatively, she developed persistent, clear fluid discharge from the incision, suggestive of a fistula, yet initial surgical re-exploration was inconclusive. The patient underwent radionuclide cisternography using 37 MBq of intrathecal Tc-99m DTPA. Standard planar scintigraphy at 1 hour and 3 hours was equivocal due to background renal activity. However, Hybrid SPECT/CT performed at 3 hours precisely localized an abnormal radiotracer tract extending from the thecal sac at L5 into the right multifidus muscle, a finding invisible on conventional imaging. Conclusion: The integration of physiological flow data from scintigraphy with the anatomical specificity of low-dose CT allows for the detection of slow-flow, occult leaks that evade MRI. In infants with distorted post-surgical anatomy, Hybrid SPECT/CT should be elevated from a problem-solving tool to a primary diagnostic modality when clinical suspicion persists. The technique facilitates targeted repair, minimizing morbidity in this vulnerable population.

Background: Differentiating early-stage multiple system atrophy-cerebellar type (MSA-C) from other ataxia syndromes presents a significant diagnostic challenge. While striatal dopaminergic denervation is a hallmark of synucleinopathies, it may be absent in the early stages of the cerebellar subtype. This study investigates the temporal dissociation between metabolic and dopaminergic biomarkers. Case Presentation: We report a 48-year-old male presenting with a 5-year history of progressive cerebellar ataxia and mild Parkinsonism, resistant to dopaminergic therapy. Written informed consent was obtained from the patient for the publication of this case details and images. To exclude mimics, a basic metabolic workup and High-resolution 3T MRI were performed. MRI revealed mild cerebellar atrophy but lacked the specific hot cross bun sign. Wilson’s disease screening was negative. Due to limited resources, advanced genetic panels for spinocerebellar ataxias were not performed. The patient underwent dual-modality molecular imaging. On Day 1, 18F-FDG PET/CT demonstrated profound hypometabolism in the cerebellum (Cerebellum/Whole-Brain SUVr: 0.68) and pons (SUVr: 0.72). Conversely, on Day 30, 99mTc-TRODAT-1 SPECT revealed robust, symmetrical striatal uptake with Specific Binding Ratios (SBR) of 1.15 (Right) and 1.12 (Left), indicating preserved presynaptic dopamine transporter density. Conclusion: This case illustrates a critical temporal dissociation in MSA-C pathophysiology: widespread pontocerebellar metabolic failure occurs prior to structural nigrostriatal degeneration. Clinicians must recognize that a normal DAT scan does not exclude MSA-C. In limited-resource settings where genetic testing is unavailable, 18F-FDG PET offers superior sensitivity in the early diagnostic window to support the diagnosis.

Background: Psoriasis vulgaris is a systemic inflammatory disease increasingly prevalent in Southeast Asia, often complicated by metabolic syndrome. While Secukinumab, an IL-17A inhibitor, is established in Western cohorts, real-world data on its efficacy in Indonesian populations with high adiposity burdens are scarce. This study evaluates the therapeutic response and safety of Secukinumab 300 mg in a Balinese cohort characterized by severe disease and metabolic risk factors. Methods: We conducted a retrospective cohort study at a tertiary referral center in Bali from January 2023 to December 2024. The study included 39 adult patients with moderate-to-severe psoriasis treated with Secukinumab 300 mg. The primary endpoint was the proportion of patients achieving a 75% reduction in the Psoriasis Area and Severity Index (PASI 75) at Week 17. Fisher’s Exact Test was employed to analyze response differences between obese and non-obese subgroups. Results: The cohort exhibited a high systemic burden: 44.2% were obese (Body Mass Index greater than or equal to 25 kg/m2), and 53.8% had concomitant psoriatic arthritis. Baseline disease severity was high with a median body surface area of 25.0%. At week 17, 32 patients (82.1%; 95% confidence interval: 67.3–91.0%) achieved PASI 75. Subgroup analysis revealed no statistically significant difference in response rates between obese and non-obese patients (p > 0.99), suggesting efficacy is maintained despite metabolic burden. No severe adverse events or discontinuations were documented in the medical records. Conclusion: Secukinumab 300 mg demonstrates substantial efficacy in an Indonesian population with a severe phenotypic profile, maintaining therapeutic clearance in metabolically compromised patients. The safety profile appears favorable, though limited by retrospective data capture.

Background: The epidemiological transition in Asia has precipitated a double burden of disease, where rapid industrialization intersects with an aging demographic to drive a surge in cardiovascular mortality. Hypertension remains the predominant modifiable risk factor in this context. While the correlation between fine particulate matter (PM2.5) and elevated blood pressure is documented in Western literature, evidence regarding Asian populations remains fragmented. This region faces a unique toxicological phenotype characterized by extreme exposure concentrations, distinct particulate composition including biomass and dust, and specific genetic susceptibilities, necessitating a dedicated regional analysis. Methods: We conducted a systematic review and meta-analysis of observational studies published between 2017 and 2024, searching PubMed, Scopus, and Embase. We critically appraised exposure assessment methods, distinguishing between satellite-based estimates and ground monitoring, and performed a quality audit using the Newcastle-Ottawa Scale. To minimize temporal bias, we stratified analyses by study design into Incident Hypertension (Cohort studies) and Prevalent Hypertension (Cross-sectional studies). Results: Nine pivotal studies encompassing over 600,000 participants from China, Taiwan, India, South Korea, and Thailand were synthesized. The random-effects meta-analysis revealed a significant pooled Hazard Ratio of 1.12 (95% CI 1.06 to 1.18) per 10 micrograms per cubic meter increase in long-term PM2.5. Heterogeneity was significant (I2 equals 90.2%), driven by regional variations. High-altitude cohorts in Tibet and high-exposure regions in India demonstrated synergistic risks with Odds Ratios exceeding 1.50 compared to moderate-exposure regions in Taiwan. Conclusion: Long-term PM2.5 exposure is a potent, independent driver of hypertension in Asia. The data suggest a synergistic interaction between hypoxia and pollution, and a non-linear dose-response curve at high concentrations. Clinicians should consider residence in high-pollution zones a cardiovascular risk enhancer equivalent to traditional risk factors.

Background: Primary squamous cell carcinoma (SCC) of the parotid gland is a rare, aggressive malignancy often requiring radical parotidectomy with facial nerve sacrifice, particularly in T4b stage disease. The utility of neoadjuvant chemotherapy (NACT) in downstaging these tumors to facilitate functional nerve preservation remains controversial and under-reported in the literature. Case presentation: A 58-year-old male presented with a fixed, rapidly enlarging left preauricular mass classified as cT4bN2M0 (Stage IVA). The tumor involved the sternocleidomastoid muscle and encased the external carotid artery. Following a multidisciplinary tumor board decision, the patient underwent an extended course of six cycles of Paclitaxel and Carboplatin. The tumor exhibited a partial clinical response and significant central necrosis on imaging. Subsequently, a total parotidectomy was performed. Despite intraoperative fragility and adherence to deep vascular structures, the main trunk and primary divisions of the facial nerve were anatomically and functionally preserved. Histopathology confirmed high-grade SCC with perineural invasion limited to the distal excised branches, achieving clear margins. The patient received 66 Gy of adjuvant radiotherapy. At the 18-month follow-up, the patient remains disease-free with House-Brackmann Grade I facial function. Conclusion: Long-term facial nerve preservation is feasible in selected cases of locally advanced parotid SCC using a multimodal approach. Extended NACT may induce tumor necrosis and facilitate dissection along the neuro-vascular interface, provided that perineural invasion does not involve the main nerve trunk.

Background: Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive soft tissue sarcomas often requiring radical excision. In the gluteal region, achieving oncological clearance for giant tumors creates massive defects characterized by dead space and tension. This study evaluates the utility of the fasciocutaneous rotational flap for immediate closure when free tissue transfer is unavailable. Case presentation: A 56-year-old female presented with a rapidly enlarging, Grade III MPNST on the right buttock measuring 18 cm in diameter. Wide local excision resulted in a defect measuring 18 cm by 16 cm by 10 cm, exposing the gluteus maximus. Due to resource limitations preventing intraoperative frozen section analysis, wide anatomical clearance was prioritized. Immediate reconstruction was performed using a random-pattern fasciocutaneous rotational flap based on inferior gluteal artery perforators. The flap arc length measured 52 cm with a 1:3.25 defect-to-arc ratio. Postoperative histopathology confirmed Grade III MPNST with positive deep margins (R1), necessitating adjuvant radiotherapy. The flap healed completely by day 14 without necrosis, and the patient was discharged on day 5. At the 3-month follow-up, the wound remained stable with no dehiscence during radiation. Conclusion: The gluteal fasciocutaneous rotational flap is a robust technique for closing massive defects where primary closure is impossible. While it provides excellent durable coverage for adjuvant therapy, the inability to confirm negative margins intraoperatively poses significant oncological risks. Immediate flap coverage should be weighed carefully against staged reconstruction in resource-stratified settings.

Background: Nasal vestibulitis is frequently regarded as a benign localized infection. However, in immunocompromised hosts, specifically those with uncontrolled diabetes mellitus, it can rapidly escalate into a life-threatening maxillofacial abscess involving the danger triangle of the face. The synergistic destructive potential of Methicillin-resistant Staphylococcus aureus (MRSA) and hyperglycemia poses a formidable challenge for reconstructive surgery due to extensive tissue necrosis and compromised microvasculature. This study evaluates the efficacy of a dual-flap approach—combining Rotation and V-Y Advancement flaps—for restoring extensive midfacial defects. Case presentation: A 51-year-old male with uncontrolled Type 2 Diabetes presented with a massive, ruptured maxillofacial abscess originating from neglected nasal vestibulitis exacerbated by rhinotillexomania. The infection resulted in extensive necrosis spanning the nasal dorsum, infraorbital regions, and forehead. Microbiological analysis confirmed MRSA. Laboratory markers indicated severe sepsis with leukocytosis of 34,840 /mm³ and hyperglycemia of 328 mg/dL. Following acute stabilization and surgical debridement, the patient sustained a complex soft-tissue defect crossing multiple aesthetic subunits. A staged reconstruction was performed three weeks post-debridement. A V-Y advancement flap was utilized for the infraorbital and medial cheek defects to minimize ectropion risk, while a rotation flap was designed for the glabella and nasal dorsum to recruit forehead tissue. Conclusion: The combination of V-Y advancement and rotation flaps provides a robust, anatomically adaptable, and aesthetically superior solution for complex midfacial defects where skin laxity is compromised. This approach allows for tension-free closure in the aesthetic subunits of the face, even in patients with compromised perfusion due to diabetes. Early recognition of MRSA in diabetic vestibulitis is critical to preventing catastrophic tissue loss.
