Abstract

Latar Belakang: Kulit berfungsi sebagai pelindung tubuh manusia dan rentan mengalami kerusakan, salah satunya luka bakar. Luka bakar disebabkan oleh trauma panas atau dingin yang memiliki risiko morbiditas dan mortalitas yang tinggi. Diabetes melitus dapat menghambat penyembuhan luka bakar dengan memperpanjang inflamasi, mengganggu proses re-epitelisasi, sintesis, dan proliferasi fibroblas. Human Bone Marrow Mesenchymal Stem Cells (hBM-MSCs) dapat mempercepat penyembuhan luka bakar pada kulit. Objektif: Penelitian ini bertujuan untuk mengetahui efek hBM-MSCs terhadap deposisi kolagen pada penyembuhan luka bakar dengan diabetes melitus. Metode: Penelitian ini dilakukan secara post-test only control group design. Penelitian ini menggunakan 30 blok parafin yang berisikan jaringan kulit luka bakar full thickness tikus diabetes melitus yang diterminasi pada hari ke-3, ke-7, dan ke-14. Terdiri dari kelompok kontrol dan perlakuan. Jaringan kulit dibuatkan preparat histologis dengan pewarnaan Picro Sirius Red untuk menilai deposisi kolagen. Data dianalisis menggunakan uji T-Independent. Hasil: Hasil penelitian menunjukkan terjadi peningkatan deposisi kolagen pada kulit tikus luka bakar full thickness diabetes mellitus setelah diberikan hBM-MSCs. Analisis statistik deposisi kolagen pada hari ke-3 dan ke-7 tidak menunjukkan peningkatan yang signifikan, sedangkan hari ke-14 terlihat peningkatan yang signifikan. Kesimpulan: hBM-MSCs berpotensi meningkatkan deposisi kolagen pada kulit luka bakar tikus diabetes melitus.

Abstract

D-galactose is a reducing sugar that induces oxidative stress by increasing the production of Reactive Oxygen Species (ROS) and Advanced Glycation End-products (AGEs), processes also associated with aging. Akar kayu kuning (Arcangelisia flava Merr.) extract contains antioxidant compounds that neutralize free radicals and mitigate oxidative stress. This study aimed to evaluate the effect of akar kayu kuning extract on the histopathological alterations of the kidneys in D-galactose-induced mice (Mus musculus). A true experimental study with a post-test-only control group design was conducted using 25 mice, divided into five groups: a negative control, a positive control (administered D-galactose at 150 mg/kgBW), and three experimental groups that received akar kayu kuning extract at doses of 250 mg/kgBW, 500 mg/kgBW, and 750 mg/kgBW following D-galactose induction. Kidney tissues were stained with hematoxylin and eosin (HE), and the extent of histopathological damage was quantified using ImageJ software. Statistical analysis using the Kruskal-Wallis test revealed significant differences between the experimental groups and the positive control (p < 0.05). The findings demonstrate that akar kayu kuning extract significantly reduces kidney histopathological damage in D-galactose-induced mice, highlighting its potential as a natural antioxidant for preventing oxidative stress-related renal impairment.

Abstract

Background: Thymic epithelial tumors (TETs) are uncommon malignancies originating in the mediastinum, characterized by considerable histopathological diversity and variable clinical trajectories. Programmed Death-Ligand 1 (PD-L1), an immune checkpoint protein, is implicated in mechanisms of tumor immune evasion. This study aimed to investigate the correlation between PD-L1 immunoexpression and distinct histopathological types, as well as the Masaoka-Koga stage, in TETs. Methods: This cross-sectional investigation analyzed 29 archival cases of TETs diagnosed between January 2019 and December 2024 at the Anatomical Pathology Laboratory of Dr. M. Djamil General Hospital Padang. Samples were procured via consecutive sampling from formalin-fixed paraffin-embedded (FFPE) tumor tissues. Histopathological classification was reassessed according to the WHO 2021 criteria. PD-L1 expression was evaluated immunohistochemically and quantified using the Tumor Proportion Score (TPS). Masaoka-Koga staging was determined from clinical records. Statistical analysis of correlations was performed using the Chi-square test. Results: PD-L1 immunoexpression was detected in the preponderance of cases. Low positive PD-L1 expression (TPS 1-49%) was observed in 82.8% of TETs, while high positive expression (TPS ≥50%) was noted in 10.3%. Thymic carcinoma constituted the most prevalent histopathological category (51.7%), and the majority of patients (91.7%) presented at an advanced Masaoka-Koga stage. Statistical analysis did not demonstrate a significant correlation between PD-L1 expression levels and histopathological type (p=0.195). Furthermore, no significant association was identified between PD-L1 expression and Masaoka-Koga stage (p=0.800). Conclusion: This study indicated that while PD-L1 is frequently expressed in TETs within this cohort, its expression level did not exhibit a significant correlation with specific histopathological subtypes or the Masaoka-Koga clinical stage. Further investigations incorporating larger sample sizes are warranted to delineate the precise role of PD-L1 within the complex biological spectrum of thymic neoplasms.

Abstract

Background: Endometrioid endometrial carcinoma (EEC) is a prevalent gynecological malignancy whose prognosis is influenced by factors including histopathological grade and lymphovascular invasion (LVI). Angiogenesis, crucial for tumor growth and metastasis, is significantly mediated by vascular endothelial growth factor (VEGF). This study aimed to investigate the expression of VEGF in EEC and its correlation with histopathological differentiation and LVI. Methods: This observational analytical study employed a cross-sectional design using 36 archival paraffin block samples of EEC diagnosed between January 2022 and December 2024 at the Anatomical Pathology Laboratory of Dr. M. Djamil General Hospital Padang. Cases were selected via simple random sampling from a population of 59. Histopathological grade (Grade 1, 2, or 3 based on FIGO architectural and nuclear criteria) and LVI (negative, focal, or substantial) were re-evaluated from Hematoxylin-Eosin (H&E) stained slides. VEGF expression was assessed by immunohistochemistry, scored semiquantitatively based on the percentage of positive tumor cells and staining intensity, and categorized as low or high. Data were analyzed using Chi-square tests, with p<0.05 considered statistically significant. Results: The mean age of patients was 54.36 years, with the highest prevalence in the 51-60 age group (41.7%). Grade 3 tumors were most common (38.9%), followed by Grade 2 (33.3%) and Grade 1 (27.8%). LVI was present in 47.2% of cases, predominantly focal (38.9%). High VEGF expression was observed in 58.3% of EEC cases. A statistically significant association was found between high VEGF expression and higher histopathological grade (p=0.000), with 66.7% of Grade 3 tumors showing high VEGF expression. No significant association was found between VEGF expression and LVI (p=0.080). Conclusion: High VEGF expression significantly correlated with higher histopathological grades in EEC, suggesting its role in tumor aggressiveness and dedifferentiation. However, a significant association with LVI was not established in this cohort. VEGF expression warrants further investigation as a potential prognostic biomarker and therapeutic target in EEC.

Abstract

Malignant peripheral nerve sheath tumor (MPNST) is a rare and aggressive group of neoplasms arising from the peripheral nervous system sheath cells (Schwann cells or perineurial cells). Malignant peripheral nerve sheath tumors are typically seen in patients aged 20–50 years, and the most common sites are the trunk and extremities. This case highlights the diagnostic complexity and distinguishes MPNST from undifferentiated carcinoma. We present a case report of a 59-year-old male patient who presented with a rapidly growing mass in the right shoulder for six months. Clinical examination on his shoulder showed a solid mass, lobulated and ulcerated, and an irregular margin measuring 16x12x5 cm. A thoracic MRI revealed a large mass, fusiform and lobulated, with dimensions of 15.02 x 15.81 x 12.65 cm. The patient underwent surgical incision biopsy of the mass. Histopathological and immunohistochemical examinations with S100 and cytokeratin (CK) markers were performed on this patient with MPNST results. The immunoprofile of MPNST showed focal positive staining for S100 marker and negative staining for CK marker. The diagnosis of malignant peripheral nerve sheath tumor can be more challenging if the histopathological examination resembles a feature of undifferentiated carcinoma, like lobulated pattern and clustering of cells with round-oval nuclei. The role of immunohistochemical examination is very important to rule out differential diagnoses.

Abstract

Background Adenoid cystic carcinoma is a malignant salivary gland tumor with unique features, including slow growth, progressive, poor prognosis, recurrence propensity, and perineural invasion tendency. SOX10 is a transcription factor expressed in the majority of tumors. SOX10 overexpression was hypothesized to play an important role in tumor-stroma interactions, especially perineural invasion and histopathological patterns.   Method A cross-sectional study was performed using 30 blocks of formalin-fixed embedded specimens previously diagnosed as salivary gland adenoid cystic carcinomas. Perineural invasion and histopathological patterns were evaluated followed by immunohistochemical staining to evaluate SOX10 expression. The staining intensity and proportion of positively stained cells in both tumor and stroma cells were grouped into high and low expression levels. Chi-square tests were used for statistical analysis.   Result The cribriform pattern was the most common histopathological pattern in both high and low SOX10 expression. The majority of tumors with high SOX10 expression (66.67% in stroma cells and 73.33% in tumor cells) were found to have more perineural invasion.   Conclusion There was a tendency for perineural invasion in tumors with high SOX10 expression, although this was not statistically significant. There was no significant association between SOX10 expression and histopathological pattern.
