RESUMO

The successful management of ASS-affected brackishwater aquaculture ponds necessitates overcoming associated environmental limitations. This study investigated the potential application of nano-biosilica from rice husk ash (RHA) and soil remediation techniques to improve the environmental quality of ASS-affected brackishwater ponds. The study followed a completely randomized design (CRD) with four treatments and three replicates. The treatments comprised applying soil remediation, nano-biosilica fertilizer, and their combination. The study generally revealed that the combination of soil remediation technique and RHA-driven nano-biosilica improved the water quality of ASS-affected brackishwater ponds. Soil remediation improved water quality by reducing acidity levels. However, excessive lime application as an integral part of the remediation might release acidity and toxic metals into water, potentially increasing calcium-phosphorus fixation. Despite liming potential negative consequences, if mixed with nano-biosilica could increase diatom-phytoplankton growth by reducing dissolved Al and Fe levels while boosting P and Si availability. Liming could also help boost diatom photosynthesis and inhibit unwanted algae blooms by decreasing water turbidity and increasing sunlight penetration. This study emphasized that the effectiveness of nano-biosilica in promoting diatom growth depends on appropriate nitrogen (N) and phosphorus (P) concentrations and ratios, which should not be a limiting factor. However, the required N/P concentration and ratio are only met if the remediation method is effectively implemented. The combination of nano-biosilica and soil remediation treatment maintained SiO2 concentrations above the average natural seawater concentration; however, availability may be limited due to complexes containing Ca, Al, Mg, and Fe. Regularly applying cost-effective nano-biosilica fertilizer in combination with N and P fertilizers is recommended to enhance water remediation efficiency by boosting Si availability and decreasing the toxicity of dissolved toxic metal ions.

RESUMO

Chronic unilateral renal obstruction, primarily caused by ureteropelvic junction obstruction (UPJO), poses challenges in determining the optimal timing for corrective surgery. The goal is to preserve renal function and alleviate symptoms, but there is no definitive diagnostic test to reliably predict the outcomes of surgery. This systematic review aimed to identify predictors for renal function recovery after pyeloplasty in order to guide effective treatment options. We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. A literature search was performed on PubMed, Embase, and Scopus using keywords related to renal function, pyeloplasty, and predictors. The search was conducted on March 10, 2022. The quality of the included studies was assessed using the Newcastle-Ottawa Scale. Out of 344 potentially relevant articles, 11 met the eligibility criteria for this study. These included 6 retrospective and 5 prospective studies, with a total of 925 participants. Most studies evaluated renal function using differential renal function (DRF). The overall quality of the included studies was considered average. The findings indicated that age at the time of surgery and gender did not significantly influence functional recovery after pyeloplasty. However, preoperative DRF consistently emerged as a critical predictor. Preoperative DRF can serve as the most common predictors used for renal function recovery following pyeloplasty. These findings contribute to understanding effective treatment options for chronic unilateral renal obstruction. However, further research for each predictor is needed to validate these predictors and their clinical utility. Cite this article as: Siregar S, Mustafa A, Steven S.

RESUMO

The incidence of nephrolithiasis in children ranges from 5 to 10% in developing countries. Etiology of nephrolithiasis in children remains largely unknown, so metabolic evaluation is indicated in all case, because of potential morbidity and recurrence. We report a case of 2,8-Dihydroxyadenine nephrolithiasis present as bilateral staghorn stone in 11 years old boy with chronic kidney disease. 2,8-Dihydroxyadenine nephrolithiasis is the result of a metabolic abnormality due to the deficiency of the enzyme adenine phosphoribosyltransferase (APRT), it is not only promote stone formation, but also induced nephropathy. Early diagnosis ensure appropriate treatment and favorable prognosis for kidney function and stone management.

RESUMO

Objective: Fournier's gangrene is a rare but life-threatening infection disease with high mortality rate. The quick Sepsis-related Organ Failure Assessment (qSOFA) is a new and simpler scoring system that may identify patients with suspected infection who are at greater risk for a poor outcome. The purpose of this study was to find out role of qSOFA in determining prognosis of Fournier's gangrene patients. Methods: This study is a case control with retrospective review of Fournier's gangrene patients treated at Hasan Sadikin Hospital from January 2013 to December 2017 who met inclusion criteria. Participants were divided into two groups according to qSOFA score as high qSOFA (2-3) and low qSOFA (0-1). Results: From 69 patients, the mortality rate was 24.6%. The sensitivity of qSOFA score to predict mortality was 88.2%; the specificity was 94.2%; positive predictive value was 83.3%; negative predictive value was 96.1%; positive likelihood ratio was 15.2; negative likelihood ratio was 0.12; and the area under the receiver operating characteristic curve of qSOFA was 94.2%. There was significant association between qSOFA scale and mortality with p-value of 0.0001. The qSOFA score has strong positive correlation with Fournier's Gangrene Severity Index (p<0.0001, r=0.704). Conclusion: qSOFA scoring system has a high prognostic value and can be used to determine prognosis of Fournier's gangrene patients.

RESUMO

Toxic materials in waste generally contain several components of the global trending pollutant category, especially PAHs and heavy metals. Bioremediation technology for waste management that utilizes microorganisms (bacteria) has not been fully capable of breaking down these toxic materials into simple and environmentally friendly chemical products. This review paper examines the potential application of a consortium of marine sponge symbionts with high performance and efficiency in removing PAHs and heavy metal contaminants. The method was carried out through a review of several related research articles by the author and published by other researchers. The results of the study conclude that the development of global trending pollutant (GTP) bioremediation technology could be carried out to increase the efficiency of remediation. Several types of marine sponge symbiont bacteria, hydrocarbonoclastic (R-1), metalloclastic (R-2), and metallo-hydro-carbonoclastic (R-3), have the potential to be applied to improve waste removal performance. A consortium of crystalline bacterial preparations is required to mobilize into GTP-exposed sites rapidly. Bacterial symbionts of marine sponges can be traced mainly to sea sponges, whose body surface is covered with mucus.

RESUMO

BACKGROUND: Varicocele is known to have impacts in infertility cases and sperm quality. This review aimed to evaluate the effects of microsurgical varicocelectomy on sperm DNA fragmentation index (DFI) and sperm parameters. METHODS: Open full English text articles from January 2017 to October 2021 were searched from online database including PubMed, EMBASE, Scopus, Cochrane Library and Google Scholar. RESULTS: Systematic search resulted in 277 potential papers. After throughout paper analysis, 5 studies were included in this review. From all five analyzed studies, microsurgical varicocelectomy was statistically proven to reduce DNA fragmentation index by 5.46% (mean difference -5.46; 95% CI: -4.79, -6.13; p < 0.00001). Moreover, the procedure also significantly improved other sperm parameters (sperm concentration +8.23%, sperm motility +7.17%, sperm progressive motility +2.77%, sperm morphology +0.64%). CONCLUSION: Microsurgical varicocelectomy significantly improves spermatogenesis as reflected by biomarkers of infertile men including semen parameters and sperm DNA fragmentation (SDF).

RESUMO

INTRODUCTION: Bladder outlet obstruction (BOO) was caused by a series of histological and biochemical changes in the bladder wall, through the inflammation process in the bladder wall, hypertrophy and fibrosis. ADSC has an important role in bladder regeneration. METHODS AND MATERIALS: This study was an experimental randomized study using male Wistar rats which were monitored at 2 and 4 weeks to determine the effect of ADSC therapy on TGF-ß1 type I collagen, and degree of fibrosis. RESULT: Rats were divided into 5 groups. In the week 2 BOO group, 1 sample included in the category of moderate fibrosis, 1 sample that was given ADSC with mild fibrosis category, 3 samples included in severe fibrosis category, 3 samples that were given ADSC included in the category of moderate fibrosis. The concentration of TGF-ß1 in the hADSC therapy group was significantly lower than the control group at the 2nd and 4th week of monitoring (p2 = 0.048, p4 = 0.048), and also with more type I collagen on 2nd and the 4th week (p2 = 0.048, p4 = 0.048). CONCLUSION: ADSC therapy can reduce the concentration of TGF-ß1, type I collagen, and degree of fibrosis in the male Wistar BOO model.

RESUMO

Testicular infarction and ischemia are rare complications of acute epididymitis. The condition is difficult to differentiate with testicular torsion clinically and radiologically. There are only a few cases that have been reported. In this study, we presented a case in a 45 years old male with acute pain in the left testicular. Left orchidectomy had been performed on the patient. Arterial thrombus and ischemia of the left testis were found by pathology examination. Although it is an uncommon case, it has been reported as a potentially serious complication of epididymitis and should be considered when acute scrotal pain is encountered.

RESUMO

Background: Hypospadias was ranked second after undescended testis as the most prevalent congenital abnormality in newborn males. Hypospadias can be successfully repaired through multiple surgeries in the majority of children. Postoperative complications were not rarely seen after surgeries, such as urethrocutaneous fistula (UCF), meatal stenosis, and glans breakdown. Tissue sealant application in hypospadias repair serves as additional suture line coverage and reduces the post surgery complications. However, the effects of sealants usage during urethroplasty are still uncertain. This review aimed to know the effects of tissue sealant usage on patients with hypospadias who undergo urethroplasty. Methods: The study was reported based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Literature was searched on PubMed, Embase, and Scopus following PRISMA guidelines. The search was conducted on October 12th, 2021, using the search term ("glue" OR "sealants" OR "tissue glue" OR "tissue sealant" OR "tissue adhesive") AND ("hypospadias" OR "urethrocutaneous fistula" OR "urethral repair" OR "urethroplasty" OR "hypospadiology"). Result: Systematic searching from all databases resulted in 160 potential articles. After a full-text review, eight articles were included in this study. Urethrocytaneous fistula complication was reported in all studies. The occurrence of complication reported by all studies was urethrocutaneous fistula. Several studies also reported tissue edema and flap-related complications. Tissue sealant had no significant effect in reducing meatal stenosis. Conclusions: This systematic review revealed additional benefits from several types of tissue sealant in hypospadias repair surgery. Fibrin sealant application over the urethroplasty suture line in hypospadias repair offers a water-proof coverage and may enhance the outcome from the surgery.

RESUMO

INTRODUCTION: Varicocele is the predominant cause of male infertility. Reactive oxygen species was found in varicocele which induce the lipid peroxidation process in the plasma membrane of spermatozoa and may cause damage to spermatozoa in semen and seminiferous tubules, disrupting spermatogenesis. Human adipose derived stem cells (hADSC) can suppress oxidative stress in some oxidative injury model. This study investigate the effect of intratesticular hADSC injection on malondialdehyde (MDA) level and spermatogenesis process by histopathological examination in the varicocele rat model. METHODS: This is an experimental study. A total sampling of 9 male Wistar rats were divided into three groups. Group I consist of 1 Wistar rats without any treatment or model (sham group), group II consist of 4 Wistar rats with varicocele model without hADSC therapy (control group), and group III consist of 4 Wistar rats with varicocele model and were given injections of 1.0×106 hADSC cells intratesticularly 30 days after model was made (therapy group). Testicular tissue was harvested for evaluation. RESULTS: In all varicocele model rats (group II and III), the result of MDA level in therapy group (2.53 mol/liter) was significantly lower than the MDA level in control group (4.43 mol/liter) (p = 0.01). On histopathological examination, the average Johnson's Score in the therapy and control group was 9.77 and 9.18, respectively. The analysis showed Johnson's score in the intervention group was significantly higher (p = 0.018). CONCLUSION: Intratesticular injection of hADSC can help reduce MDA levels and improve spermatogenesis process, which is damaged by varicoceles.

RESUMO

BACKGROUND AND AIM: Fournier gangrene (FG) is a necrotizing fasciitis of perineal and/or genital regions that may progressively spread; necrotic tissue may cause morbidity and mortality related to sepsis and multi-organ dysfunction. Surgical intervention required for patients with Fournier gangrene may vary according to the severity of the infection. A Fournier Gangrene Severity Index (FGSI) has been devised to assess the risk of mortality in patients with Fournier gangrene. The aim of this study was to validate the implementation of the FGSI in predicting mortality of FG patients in our hospital. METHODS: A retrospective study was performed on all patients with Fournier gangrene admitted and treated in Hasan Sadikin General Hospital during 2015-2019. Data were collected from the medical records of the emergency room and outpatient clinics. Sociodemographic variables, preexisting comorbidities, outcome, management, and FGSI score were included as variables. RESULTS: In this study, 83 patients were included from the period 2015-2019, divided into two groups. From the Charlson Comorbidity Index, we found the first group average score was 2.5 (0-9), and the second group this was 2 (1-8). From the FGSI, in the first group, we found the average score was 5.5 (2-15), and the average was 14 (10-19) in the second group, which is significantly higher than the first group (p = 0.001). CONCLUSION: We find that the FGSI score system is a good tool for predicting severity of the disease and mortality risk of the patients, which is consistent with findings in other studies.

RESUMO

INTRODUCTION: Cervical cancer is the 3rd most common cancer in women. In late stages, obstructive uropathy due to mass infiltration is common and the mainstay of treatment for this condition is palliative urinary diversion through percutaneous nephrostomy. Nevertheless, complications due to nephrostomy may have adverse effects on some patients. Further study is necessary to determine whether nephrostomy is suitable for all cervical cancer patients with obstructive uropathy. This study aims to identify the determinants of survival rate of cervical cancer patients undergoing nephrostomy for obstructive uropathy and determine the group of cervical cancer patients that would benefit the most from nephrostomy. METHODS: Data were obtained from medical records of cervical cancer patients in Hasan Sadikin Central Public Hospital from January 2018 to December 2019. Log-rank analysis was performed to assess the survival rate of patients based on clinical conditions (age, metastasis, and ECOG performance status) and initial laboratory results (hemoglobin, leukocyte, thrombocyte and blood acidity). RESULTS: A total of 163 cases were identified from the medical records, with a median survival of 5(1-17) months. The results of the analysis showed that the survival rates of cervical cancer patients undergoing nephrostomy were significantly affected by age (p = 0.0001), metastasis (p = 0.0001), and ECOG performance status (p = 0.0001), while laboratory findings were not significant factors affecting survival (pHb=0.501; pLeu=0.634; pTr=0.077; pBGA=0.687). CONCLUSION: The survival after nephrostomy in advanced cervical cancer patients is largely affected by age, metastasis, and performance status. The choices of doing nephrostomy in those patients should be considering those factors to maximize the benefit over the risk of complications.

RESUMO

An avulsion is very rare and the most serious complication that may occur during ureteroscopy in 0.06-0.45% of patients during the ureteral stone procedure. A sixty years-old female with a small stone in the upper third of the right ureter with high-grade hydronephrosis and underwent a ureteroscopy procedure. During withdrawal of the scope, the ureter was brought out in urethral meatus, with inverted fashion, nearly the whole length of the ureter was avulsed out. A nephrectomy of the right kidney was then performed. Knowledge about signs of the ureteral avulsion, pitfalls when to stop, and treatments is really important.

RESUMO

Penile strangulation by metallic ring is an emergency situation which requires urgent management. Strangulation of the penis usually performed in order to increase sexual performance or because underlying mental disorder or paraphilia. It is an uncommon urological emergency, if not treated as soon as possible it can lead to complications such as gangrene and amputation of the penis. There is no standard of care that has been found to be superior, with each case managed individually according to its clinical findings and operative settings. In this study, we present four cases of penile strangulation in last two years in a tertiary care hospital.

RESUMO

Renoduodenal fistula is a rare condition where a pathological tract is formed between the kidney and duodenum. This condition is caused by various etiologies, such as tuberculosis, malignancy, percutaneous nephrostomy procedure, cryoablation procedure in malignancy, and chronic infection. In this case, we report a case renoduodenal fistula caused by large staghorn calculus, precipitated by a previous history of trauma. Renoduodenal fistula is a rare condition that often presents without symptoms. This condition can be caused by chronic infection of the kidney, and one of the etiology is an infected large staghorn calculus.

RESUMO

INTRODUCTION: Testicular torsion is a sudden rotation of the testis towards its axis, which causes the twisting of the spermatic cord. Post-detorsion reperfusion will cause inflammation and trigger oxidative stress, which generates reactive oxygen species (ROS). Malondialdehyde (MDA) is an organic compound formed from ROS frequently used as an oxidative stress biomarker during ischemia and ischemia-reperfusion injury. In some organs, stem cell administration on the damaged organ is essential in preventing cellular damage and death. This study aimed to learn about the effect of hADSC administration on an ischemia-reperfusion injury. MATERIAL AND METHODS: A total of 22 Wistar rats divided into 5 groups, two groups each consist of 5 male Wistar rats with testicular torsion model without hADSC therapy (group I), while 2 other groups consist of 5 rats with testicular torsion model were given 1.0×106 cells intratesticular hADSC injection 30 minutes after testicular detorsion (group II). Both groups were euthanized at 1 and 4 weeks of observation. The last group consists of 2 rats without any treatment or model (negative control group). Following euthanasia, testicular tissue was harvested for MDA expression measurement using ELISA and histopathological examination. Statistical analysis using an one way ANOVA was done with SPSS version 21.0. RESULTS: The result of MDA examination using the ELISA method has shown a concentration difference between group I (control) and group II (hADSC treatment). Testicular MDA concentration in the treatment group was significantly lower on the 1st and 4th week of observation (p2=0.000, p4=0.016). Post hoc analysis showed no statistically different between therapy and healthy group (p=0.972). On histopathological examination, Johnsen score in the treatment group was significantly higher on the 4th week of observation (p=0.044). Post hoc analysis showed no statistically different between therapy and healthy group (p=0.195). CONCLUSION: Intratesticular hADSC administration can inhibit ROS formation due to ischemia-reperfusion injury in testicular tissue after testicular detorsion in Wistar rats.

RESUMO

BACKGROUND: This study aimed to assess the effects of exogenous SOD administration on prostate cancer cell line (PC-3) apoptosis via the intrinsic pathway by examining the expression of manganese superoxide dismutase (MnSOD), caspase-3, and apoptosis index of the PC-3 cell line. METHODS: We used the prostate cancer cells from secondary prostate cancer cell lines (PC-3) derived from castration refractory prostate cancer (CRPC), cell differentiation grade IV, and had metastasized to the bone from the American Type Culture Collection (ATCC, Rockville, MD, USA). Superoxide dismutase (SOD) is derived from extracts of melon seeds and wheat gliadin biopolymer, and divided into 62.5 mg/mL, 83 mg/mL, 125 mg/mL, and 250 mg/mL doses. Expression of MnSOD was measured by immunohistochemistry (IHC). Expression of caspase-3 was measured using Western Blot method. Apoptotic index is calculated based on the reaction introduction 3OH end of fragmentation of DNA by the enzyme terminal transferase in preparations with TUNEL staining reagents. A one-way ANOVA test and Pearson correlation test were used to determine the relationship between SOD with expression of caspase-3 and apoptotic index. RESULTS: SOD extract significantly increased the expression of caspase-3 (P=0.016) and the apoptotic index (P=0.000) (P<0.05). There was a correlation between the increased doses of SOD extract and the apoptosis index (P=0.015; r=0.679) and between the increased caspase-3 expression and the apoptosis index (P=0.015; r=0.682). CONCLUSION: Administration of superoxide dismutase (SOD) increased apoptosis in a prostate cancer cell line (PC-3) through the increased expression of caspase-3. Superoxide dismutase (SOD) can be considered as a therapy for late-stage prostate cancer that had been progressed to hormone resistant and metastasized and promote apoptosis in those prostate cancer cells.

RESUMO

INTRODUCTION: Prolonged obstruction in UPJO would lead to kidney destruction. It is important to find a non-invasive biomarker for early detection of renal impairment before definitive treatment for UPJO. In this study, we aim to evaluate the role of urinary cytochrome c and caspase-3 as a novel biomarker to predict renal function impairment in a UPJO model in Wistar rats. METHODS: Twenty-five male Wistar rats were separated into 3 groups. Group I consists of 5 rats without any treatment or model, group II consists of 5 rats (sham group), and group III consists of 15 rats with the unilateral partial ureteral obstruction model. After 4, 15, and 21 days of observation, the urine was collected and rats were sacrificed to collect the glomerular count in the kidney. Measurement of cytochrome c and caspase-3 was done using the ELISA method, while the glomerular count was done using a light microscope. Data were analyzed using factorial repeated measures ANOVA test and correlation test with Pearson and processed using SPSS version 20.0. RESULTS: The UPJO group has a significant increase in cytochrome c concentration and caspase-3 concentration compared to the control group and sham group (p<0.05). There was a significant decrease in the normal glomerulus count of the UPJO group (p<0.05). There was a significant relationship between the decrease in glomerulus count with the concentration of cytochrome c and caspase-3 in the UPJO group. CONCLUSION: There was a significant relationship between the decrease in glomerulus count with the increase in the concentration of cytochrome c and caspase-3 in the UPJO group.
