A complex mechanism is involved in the formation of reactive oxygen species (ROS), release of inflammatory mediators, and neutrophil activation. One strategy to reduce the damage is administering selenium, an antioxidant enzyme component that can bind ROS and protect cells. This study aimed to compare the degree of lung injury due to limb IRI in Sprague-Dawley (SD) rats with selenium administration versus those without selenium treatment. Materials and Methods: Fifteen male SD rats were divided into three groups: the control group (Group A), the ischemia-reperfusion with pre-reperfusion selenium (Group B), and the ischemia-reperfusion with post-reperfusion selenium (Group C). All animals underwent two hours of limb ischemia and three hours of reperfusion. Selenium was given intravenously at a dose of 0.2 mg/kg body weight. After reperfusion, lung specimens were histopathologically examined. Results: The median degree of lung injury was severe in Group A, mild in Group B, and moderate in Group C (P=0.01). Post hoc analysis revealed a significant difference in the degree of lung injury between Groups A and B (P=0.01), while a comparison between Groups A and C (P=0.06) and Groups B and C (P=0.31) revealed no significant difference. Conclusion: The administration of pre-reperfusion selenium significantly decreases lung injury induced by limb ischemia-reperfusion in SD rats.

Excessive scarring significantly affects the patientʹs quality of life, both physically and psychologically, and can also cause pain, pruritus, and contractures and cost a considerable amount of money. Therefore, it is essential to find dressings that improve a patient's prognosis. Topical therapy for treating scars is becoming popular because it is easy to use, convenient, non-invasive, and relatively inexpensive. However, no single therapy provides optimal results to eliminate hypertrophic scar formation. For most people in the world, herbs are easier to obtain because they are widely available at relatively affordable prices, so herbal therapy is still the main choice in wound healing management. Nowadays, the selection of natural ingredients such as Royal Jelly (RJ) has increased in popularity and is in demand by the public for improving the healing of surgical wounds. The study found that the flavonoid content in the sample was equivalent to quercetin and that the total phenol content in the royal jelly extract ranged from 1.41% to 1.66%. The stability test showed that the royal jelly was stable in different conditions for up to 28 days, with no significant changes observed in pH, color, smell, texture, or spreadability.

Human papillomavirus (HPV) can be transmitted sexually and causes cervical malignancies in women.... more Human papillomavirus (HPV) can be transmitted sexually and causes cervical malignancies in women. Among the risk factors, sexually transmitted infections (STIs) caused by bacteria have raised concerns because they are asymptomatic and persistent and can increase the risk of HPV infection. This study assessed the correlation among Ureaplasma urealyticum, Ureaplasma parvum, Chlamydia trachomatis, and Mycoplasma hominis infections towards abnormal cervical cells positive for HPV. Seventy outpatients at the Colposcopy Outpatient Clinic, Dr. Cipto Mangunkusumo Hospital in Jakarta, Indonesia, were enrolled in this cross-sectional study. Viruses and bacteria were detected using polymerase chain reaction and compared with liquid-based cytology results for cervical cytology. Of the 70 patients, 24 (34.28%) showed abnormal cervical cytology. Among those with abnormal cervical cytology, C.trachomatis was reported in 1 patient (4.2%), M.hominis in 6 patients (25%), U.urealyticum in 13 patients ...

Methods: A cross-sectional, analytical study was conducted comprising 34 samples of histologically-confirmed diagnosis of SIP. The samples were further grouped into 2 groups: 20 samples without associated dysplastic changes, and 14 samples with associated dysplastic changes. The numbers of FoxM1 positively-expressed cells, EGFR mutation, and HPV status were compared among two groups using appropriate comparative statistics. Results: There was statistically-significant difference of FoxM1 expression between SIP and SIP with dysplasia (10% vs 100%; p<0.001). EGFR mutation was identified in 6 samples (30.0%) of the SIP and 5 samples (35.7%) of SIP with dysplasia. No difference of EGFR mutant proportion among two groups. HPV DNA was detected in 5 samples (25.0%) of SIP versus 9 samples (64.3%) of SIP with dysplasia. There was significant difference of HPV status among two groups (p=0.022). The high-risk subtypes were found in most HPV positive samples (57.1%), while low-risk subtypes and out panel subtypes were found 14.3% and 21.4%, respectively. Conclusions: FoxM1 was overexpressed in SIP with malignant transformation. FoxM1 along with HPV status is associated with dysplastic changes in the SIP. FoxM1 immunostaining is potential to be a biomarker of malignant transformation in SIP.

Almost always unilateral on diagnosis, JNAs are locally invasive and may extend across the midline, giving a false bilateral appearance; as such, true bilateral JNA is exceedingly rare. We present a recent case of true bilateral JNA. Methods: Single case report of a patient with bilateral JNA, including clinical presentation, diagnosis, and management. Results: The patient presented with unilateral nasal obstruction and recurrent epistaxis. Computed tomography and magnetic resonance imaging demonstrated bilateral, noncontiguous masses. Angiography revealed independent vascular supplies from each respective side with no bilateral supply noted. The patient underwent preoperative embolization followed by endoscopic surgical removal of the larger mass; no complications were noted. Follow-up at 2 years demonstrated no recurrence or growth. Conclusion: The vast majority of JNAs are unilateral, though invasive growth to the contralateral side may appear "bilateral" in presentation. Proper identification of true bilateral JNA is helpful in guiding management, wherein excision of both tumors may not be necessary.

EBV-DNA load can be used for early diagnosis and may have prognostic value. In this study, EBV-DNA load was evaluated in minimal invasive nasopharyngeal (NP) brushings and whole blood for initial diagnosis and therapy assessment against the standard-of-care diagnosis by biopsy with EBV-RISH and standard EBV-IgA serology.Experimental Design: NP brushings and blood samples were collected from 289 consecutive ENT patients suspected of NPCs and 53 local healthy controls. EBV-DNA load was quantified by real-time PCR and serology by peptide-based EBV-IgA ELISA. Tissue biopsies were examined by routine histochemistry and by EBER RNA in situ hybridization.Results: Repeated NP brushing was well tolerated by patients and revealed high viral load in the 228 NPC cases at diagnosis than 61 non-NPC cancer cases and healthy controls (P < 0.001). The diagnostic valu...

Epstein-Barr virus (EBV) gene products are present in all tumor cells. Early-stage NPC diagnosis is clinically important but difficult due to non-specific symptoms. In patients suspected of having NPC, nasopharyngeal (NP) brush-cytology may provide a simple non-invasive procedure for rapid on-site detection of NPC tumour cells that can be combined with EBV markers. Methods: Patients (N=83) suspected of having NPC underwent nasoendoscopy-guided NP brushing before a biopsy from clinically suspicious areas. The loaded brush was first smeared onto glass slides that were directly immersed in ethanol, followed by Papanicolaou (PAP) staining and on-site interpretation of tumour cell presence. Thereafter, slides were used for EBER RNA in situ hybridization (EBER-ISH) and LMP-1 immunocytochemistry (ICC). The brush left-over was used for EBV-DNA load measurement using real-time PCR. Biopsy specimens were taken from the same NP site and processed for routine pathology and EBER-ISH on tissue sections. Result: Morphological detection of NPC tumour cells on PAP-stained brush-smears gave a sensitivity and specificity of 87% and 100%, respectively. EBER-RISH and LMP1 ICC combined showed 100% positivity for NPC cases. Expression of LMP-1 was detected in 77.8% of cases. Median EBV-DNA load in left-over brush material from NPC cases was 5.06 × 10 6 copies/brush (range 777 to 242,400,000 copies/brush), whereas median value in non-NPC cases was 4.4 x 10 3 copies/brush (range 484-297,200; P < 0.001). Conclusion: Minimal invasive NP-brush cytology with conventional PAP staining allows rapid, simple and cheap "on site" detection of NPC tumour cells in suspected NP lesions. The method can be modified for direct demonstration of EBV involvement using EBER-ISH and LMP1-ICC or EBV-DNA load measurement. This NP brush procedure may be useful for primary screening in patients considered at risk for NPC.

Little is known regarding the potential of these markers in predicting cancer metastasis in Laryngeal Squamous Cell Carcinoma (LSCC). Therefore, this study aimed to dissect the potential of these markers in predicting the lymph node metastasis in LSCC patients. Methods: Sixty tissue samples were obtained from the patients diagnosed pathologically with LSCC who underwent partial or total laryngectomy. The expression of MMP-9 and CCR7 was measured using the immunohistochemistry staining in the tissue samples of LSCC patients. The ROC (receiver operating characteristic) curve was used to determine the most significant cutoff points of expression according to the highest sensitivity and specificity of both the markers to predict the lymph node metastasis in LSCC. Then, the relationship between the clinicopathology features and the expression of MMP-9 and CCR7 was evaluated. Results: The expression of both MMP-9 and CCR7 was significantly correlated with the lymph node metastasis in LSCC (P<0.001). Furthermore, CCR7 expression exhibited the highest prediction accuracy (AUC 95.7%) and sensitivity (100%) in predicting the lymph node metastasis in LSCC compared to that of MMP-9 (AUC 92.9%, sensitivity 90%). We also found that patients with larger tumor size (> 4 cm) had significantly higher expression of MMP-9 and CCR7 (P<0.002 and P<0.001, respectively). The Elevated expression level of CCR7 statistically correlated with higher MMP-9 expression (P<0.001). Conclusion: MMP-9 and CCR7 might be beneficial as predictors of lymph node metastasis in LSCC patients.

Glutamine supplementation protects cardiac cells during cardiac ischemia. This study analysed the correlation between cardiac index (CI), plasma troponin I, myocardial histopathology, CPB and AoX duration in low ejection fraction patients receiving glutamine and no glutamine undergoing elective on-pump CABG. Material and Methods: This was a secondary analysis of a double-blind, randomised controlled trial of 60 patients, split into control and intervention (glutamine) groups. Glutamine was administered at a dose of 0.5 g/kg/24 hours. There were 29 patients in each respective groups after a total of two patients dropped out. Results: A negative correlation (p = 0.037) was observed between CPB duration and CI at 6 hours after CPB in the glutamine group. A positive correlation (p = 0.002) was also observed between AoX duration and plasma troponin I at 6 hours after CPB in the control group. However, no correlation was observed between myocardial histopathology and plasma troponin I level at 5 minutes after CPB. Conclusion: Significant negative correlation between CPB duration and CI at 6 hours after CPB in the glutamine group, along with significant positive correlation between AoX duration and plasma troponin I level at 6 hours after CPB in the control group demonstrated the myocardial protection qualities of intravenous glutamine administration in patients with low ejection fraction undergoing elective on-pump CABG surgeries.

Most cases are detected at an advanced stage, and recurrences are common. Vascular endothelial growth factor (VEGF) and osteopontin (OPN) are important markers in tumorigenesis that serve as prognostic predictors. This study aims to determine the correlation of VEGF and OPN expression with 3-year progression-free survival (PFS). Material and methods: This retrospective cohort study analyzed 155 patients with locally advanced NPC. Data were obtained from medical records between 2015 and 2017. The locally advanced sample of this disease that met the inclusion criteria was stained with H&E before being prepared in a paraffin block. Furthermore, the immunohistochemistry staining results for VEGF and OPN were observed with ImageJ 1.50i and calculated semi-quantitatively using the histoscore. Results: The 3-year PFS obtained was 39%, with a median of 23 months. Vascular endothelial growth factor expression was detected in 113 of 155 samples (72.9%), while positive OPN expression was discovered in 99 of 155 samples (63.8%). There was a correlation between VEGF (p = 0.747) and OPN expression (p = 0.584) and 3-year PFS. Positive VEGF and OPN expression in the subgroup of patients with stage IVB and N3 tumors was related to improved 3-year PFS (p < 0.05). This was similar to the positive VEGF expression in the subgroup of patients receiving neoadjuvant chemotherapy (p < 0.05). Conclusions: Vascular endothelial growth factor and OPN remained potential prognostic predictors in NPC. Patients with positive VEGF and OPN expression in N3, IVB, and neoadjuvant treatment had significantly improved 3-year PFS.

Patients and Methods: A pre-post test study with umbilical cord serum (UCS) eye drop for ocular SJS patient with moderate to severe dry eyes. Study was conducted at Kirana Cipto Mangunkusumo General Hospital from June 2020 to December 2020. A total of five patients (five eyes) with a diagnosis of SJS more than 6 months, dry eye symptoms, and abnormal tear stability test results were included in the study. Each patient was asked to instill UCS drop into the affected eye six times daily. Evaluation of ocular symptoms with ocular surface disease index (OSDI) questionnaires, non-invasive tear break-up time (NIBUT), Schirmer I, and keratoepitheliopathy scores was administered before applying UCS drop and at week 2 and 4 of eye drop use. Results: From June 2020 to December 2020, five eyes of five patients were evaluated in this study. Patients were aged from 22 to 71 years old with history of SJS over periods from 1 to 35 years. Three patients underwent ocular surgeries prior to the study. After four weeks of treatment, symptoms score, Schirmer I, and keratoepitheliopathy scores improved significantly, while NIBUT scores improved insignificantly. No side effects were noted during treatment. Conclusion: Administration of UCS eye drop was effective in improving symptoms and signs of dry eye in chronic SJS patients.

This study determines whether intravenous glutamine could protect the myocardium during on-pump CABG in patients with low EF. Materials and Methods: This was a double-blind, randomized controlled trial to assess glutamine as a myocardial protector during on-pump CABG in patients with left ventricle EF of 31-50%, conducted from January to October 2021. Patients in the glutamine group (n = 30) received 0.5 g/kg of 20% glutamine solution diluted with 0.9% NaCl up to 500 mL in total volume over a period of 24 hours. Patients in the control group (n = 30) received 0.9% NaCl over the same period. The primary outcomes were plasma troponin I and plasma glutamine levels. Secondary outcomes included α-ketoglutarate (α-KG) levels and histopathology scoring of the right atrial appendage tissue, plasma lactate levels, hemodynamic measurement, and morbidity. Results: Twenty-nine patients from each group (58 in total) were included in the analysis. Plasma troponin I levels at 6 and 24 hours after cardiopulmonary bypass (CPB) were significantly lower in the glutamine than the control group (mean 3.43 ± 1.51 ng/mL vs mean 4.41 ± 1.89 ng/mL; p = 0.034; median 3.08 ng/mL [min-max: 1.30-6.59] vs median 3.77 ng/mL [min-max: 0.00-36.53]; p = 0.038, respectively). Plasma glutamine levels at 24 hours after CPB were significantly higher in the glutamine than the control group (mean 935.42 ± 319.10 μmol/L vs mean 634.79 ± 243.89 μmol/L, p = 0.001). Plasma lactate levels at 6 and 24 hours after CPB were significantly lower in the glutamine than the control group (median 5.30 mmol/L [min-max: 1.20-9.50] vs median 5.70 mmol/L [minmax: 2.80-11.30], p = 0.042; mean 2.08 ± 0.67 mmol/L vs mean 2.46 ± 0.69 mmol/L, p = 0.044, respectively). Myocardial injury score was significantly lower in the glutamine than the control group (mean 1.30 ± 0.24 vs mean 1.48 ± 0.26, p = 0.011). Conclusion: Perioperative administration of 0.5 g/kg intravenous glutamine solution over the period of 24 hours has myocardial protection effect in patients with low EF who undergo elective on-pump CABG.

In this latent infection various EBV oncoproteins such as EBNA1 and LMP1 was expressed. EBV oncoproteins could theoretically recruit immune cells, which might help to control cancer. Therefore, this study was aimed to elucidate the association with EBV oncoproteins (EBNA1 and LMP1), immune markers (CD4, CD8, and FOXP3) from nasopharyngeal cancer microenvironment with tumor progression. Method Nasopharyngeal biopsy was obtained from patients suspected to have nasopharyngeal cancer. Those samples with microscopically confirmed nasopharyngeal cancer were tested for EBNA1, LMP1, CD4, CD8, and FOXP3 concentration with ELISA, then verified with IHC. Each patient tumor volume was assessed for primary nasopharyngeal tumor volume (GTVp) and neck nodal metastases tumor volume (GTVn). Correlation test with Spearman correlation and scatterplot were carried out. Result Total 23 samples with nasopharyngeal cancer...
