Acute pancreatitis is one of the most common causes of hospitalisation from gastrointestinal diseases. The causes of pancreatitis vary between countries. Acute pancreatitis is classified based on Revised Atlanta classification 2013 as mild, moderately severe and severe acute pancreatitis. Acute pancreatic severity can be stratified by scoring systems such as Ranson’s score, BISAP score, APACHE-II score, SOFA score. In severe acute pancreatitis, to diagnose, abdominal pain raised amylase or lipase, supported imaging finding and organ failure. Organ failure can be diagnosed by using Modified Marshall Scoring System. Management is started conservatively, which are fluid resuscitation, enteral nutrition, analgesics, and antibiotics. Surgical management is indicated when infected pancreas necrosis is detected. In this review, we will discuss the current management based on recent research.

BACKGROUND: Over the past decades, the study of the microenvironment of cancer has supported the hypothesis between inflammation and cancer. Previous studies have demonstrated a promising value of platelet-to-lymphocyte (PLR) and neutrophil-to-lymphocyte ratio (NLR) as a systemic inflammatory response in prostate cancer. AIM: To evaluate their pre-biopsy values of PLR and NLR in predicting prostate cancer. MATERIAL AND METHODS: This is a diagnostic study with retrospective design. We included all benign prostatic hyperplasia (BPH) and prostate cancer (PCa) patients who underwent prostate biopsy in Adam Malik Hospital between August 2011 and August 2015. We used PSA value above 4 ng/dL as the threshold for the biopsy candidates. The relationship between pre-biopsy variables affecting the percentage of prostate cancer risk was evaluated, including age, prostate-specific antigen (PSA) level, and estimated prostate volume (EPV). The PLR and NLR were calculated from the ratio of related platelets or absolute neutrophil counts with their absolute lymphocyte counts. The values then analysed to evaluate their associations with the diagnosis of BPH and PCa. RESULTS: Out of 298 patients included in this study, we defined two groups consist of 126 (42.3%) BPH and 172 PCa (57.7%) patients. Mean age for both groups are 66.36 ± 7.53 and 67.99 ± 7.48 years old (p = 0.64), respectively. There are statistically significant differences noted from both BPH and PCa groups in terms of PSA (19.28 ± 27.11 ng/dL vs 40.19 ± 49.39 ng/dL), EPV  (49.39 ± 23.51 cc vs 58.10 ± 30.54 cc), PLR (160.27 ± 98.96 vs 169.55 ± 78.07), and NLR (3.57 ± 3.23 vs 4.22 ± 2.59) features of both BPH and PCa groups respectively (p < 0.05). A Receiver Operating Characteristics (ROC) analysis was performed for PLR and NLR in analysing their value in predicting prostate cancer. The Area Under the Curve (AUC) of PLR is 57.9% with a sensitivity of 56.4% and specificity of 55.6% in the cut-off point of 143 (p = 0.02). The NLR cut-off point of 3.08 gives 62.8% AUC with 64.5% sensitivity and 63.5% specificity. These AUCs were comparable with the AUC of PSA alone (68.5%). We performed logistic regression between PSA, PLR, and NLR with result in the exclusion of PLR if calculated conjunctively. Therefore, NLR has a promising performance in predicting PCa in patients with PSA above 4 ng/dL (OR = 3.2; 95% CI: 1.96-5.11). We found as many as 80 (63.5%) patients with benign biopsy results with negative NLR value in this study. CONCLUSION: NLR has promising value in predicting prostate cancer. A further prospective study in validating its diagnostic value was needed.

Coronaviruses commonly cause mild infections, but recently severe acute respiratory syndrome-coronavirus (SARS-CoV)-2 caused a pandemic of coronavirus disease 2019 (COVID-19). A total of 3,181,642 cases were confirmed globally. Gastrointestinal tract may be involved in COVID-19 due to the presence of angiotensin converting enzyme-2 (ACE2) and transmembrane protease serine 2 (TMPRSS2) in small intestine and colon which are mandatory for SARS-CoV-2 invasion. A proportion of patients with COVID-19 had gastrointestinal manifestation without respiratory symptoms. Viable virus can also be isolated from feces of patients. Fecal-oral transmission should be considered in controlling disease spreading. Fecal examination may also be considered to diagnose COVID-19, especially in areas with limited personal protective equipment.

Coronavirus Disease (COVID)-19 is a pandemic since March 11, 2020. The total case is more than a half million worldwide. Liver injury is quite common in COVID-19 patients. Direct viral infection is possible due to the presence of angiotensin converting enzyme 2 in cholangiocytes and hepatocytes. Other proposed mechanisms are virus-induced cytopathic effects, inflammation process, hypoxia and shock, increased apoptotic activity, increased positive end expiratory effect, and drug-induced. The manifestation of liver injury is mild and transient with elevated liver enzymes, bilirubin, and gamma-glutamyl transferase levels. Deterioration of liver function can occur in subjects with COVID-19 and underlying liver injury. The management is principally supportive. Hepatoprotective drugs may be administered in severe cases.

Bladder cancer is one of the most common urinary tract cancers. The main risk factors for bladder cancer are tobacco usage, aging, gender, exposure to chemicals and drugs such as cyclophosphamide and chlornaphazine, chronic bladder problems, and genetics. Genetic factors continue to be studied including vascular endothelial growth factor (VEGF) gene polymorphism. Overexpression of VEGF is known to be higher in bladder cancer patient than healthy individual. It is also associated with tumor progression, metastasis, recurrence, and survival since VEGF and its receptor play a key role in angiogenesis. Many studies evaluated the relationship between VEGF polymorphism and the risk of bladder cancer, but the results were inconsistent because of ethnicity and geographical influences. The present study aims to raise knowledge about the role of VEGF polymorphisms on risk of bladder cancer.

Background: Kidney stones (nephrolithiasis) affect around 5% of the world's population. Some medical disorders, like obesity or diabetes, have increased the incidence and prevalence of nephrolithiasis. In addition, chronic inflammation and infection are frequently linked to kidney stone formation. Urothelial cell proliferation may change as a result of chronic inflammation, tumors will therefore develop as a result of this. The correlation between nephrolithiasis and renal cell cancer can also be explained by shared risk factors. At Adam Malik General Hospital, we strive to identify the risk factor for stoneinduced renal cell cancer.Methods: This study was carried out at Adam Malik General Hospital by collecting medical record reports from patients who had nephrectomy for nephrolithiasis between July 2014 and August 2020. A variety of information was obtained, including identification, smoking status, body mass index (BMI), hypertension, diabetes mellitus, and nephrolithiasis history. The histopathological examination of cancer patients was used to determine adjusted odds ratios (ORs) both separately and in combination with other variables. Age, smoking status, BMI, hypertension, and diabetes mellitus all influenced the OR. The single variable was examined using Chi-square test, and the multivariate analysis was carried out using linear regression.Results: A total of 84 patients who underwent nephrectomy due to nephrolithiasis were included in the study, with an average age of 48.77 ± 7.23 years old; 48 (60%) of those were aged < 55 years old.In this study, 52 male patients (63.4%) and 16 patients (20%) were found to have renal cell carcinoma. Univariate analysis showed that the OR of patients with familial history of cancer was 4.5 (95% confidence interval (CI) 2.17 -19.8), and the OR for smokers was 1.54 (95% CI 1.42 -1.68). Similar results were shown in patients with hypertension and urinary tract infections due to stones. Nephrolithiasis patients with hypertension were 2.56 (95% CI 1.075 -6.106) times more likely to develop a malignancy, while patients who had an infection due to a urinary tract stone were 2.85 (95% CI 1.37 -5.92) times more likely to develop renal cell carcinoma compared to its counterpart. Both have a P-value of less than 0.05. Contrarily, alcoholism and frequent nonsteroidal anti-inflammatory drugs (NSAIDs) user results were different. Both have a P-value of 0.264 and 0.07, respectively. Furthermore, diabetes mellitus type 2 and BMI over 25 are not statistically significant, with a P-value of 0.341 and 0.12, respectively. In multivariable-adjusted analyses, participants with a family history of cancer and recurrent urinary tract infection due to urinary tract stones had a statistically significant increase in overall renal cell carcinoma risk (hazard ratio (HR): 1.39, 95% CI 1.05 -1.84 and HR: 1.12, 95% CI 1.05 -1.34). Conclusion:Kidney stone and renal cell carcinoma are significantly correlated due to recurrent urinary tract infection and familial history of cancer, which increases renal ...

Introduction: Penile cancer is a moderately common malignancy in developing countries. Metastasis to regional lymph nodes is an essential factor in a patient’s prognosis, as its occurrence predicts poor patient prognosis. As micro-metastasis occurs in more than 25% of cases, the need for more accessible diagnostic tools is necessary. Ki-67 is commonly used as a marker of proliferation associated with tumor grade and lymph node metastasis. Methods: Samples were taken from penile cancer patients between 2013 to 2018, in the form of formalin-fixed paraffin-embedded (FFPE) blocks were analyzed. Patient demographic data, current and pre-cancer condition, cancer staging, outcomes, and other results of adjuncts and treatment modalities were obtained from medical records. Immunohistochemistry analysis was carried out on FFPE preparations. Under 20% of nuclei stained was considered as low-expression and more than 20% of nuclei stained was considered as Ki-67 over-expression. Data processing and analysis were carried out using SPSS software.  Results: In total, 48 FFPE samples were analyzed, with a mean patient age of 50.79 (±9.51 SD). For all patients, the type of pathology was squamous cell carcinoma. Node metastasis was positive in 34 patients (70.8%) and negative in 14 patients (29.2%). Statistical analysis was carried out using the Chi-Square test, resulting in a significant correlation between the expression of Ki-67 and lymph node metastasis in penile squamous cell carcinoma (p=0.045). Conclusion: Over-expression of Ki-67 were found in penile cancer patients with lymph node metastasis. Therefore, Ki-67 might be useful in predicting lymph node metastasis in penile cancer patients.

BACKGROUND:Bladder cancer is the 9th most frequent cancer worldwide. Ki-67 is immunohistochemistry marker that is predictive of cancer cell proliferation. The expression of Ki-67 is associated with poor prognosis in several types of malignancy, yet the value of Ki-67 as the prognostic factor in bladder cancer remains controversial.AIM:This study is aimed to investigate the association between Ki-67 expression with muscle-invasive bladder cancer (MIBC) and non-muscle invasive bladder cancer (NMIBC).METHODS:This was a case-control study with a retrospective design. The study was conducted at the Department of Pathology, University of Sumatera Utara, Indonesia. Samples were paraffin blocks from patients diagnosed with bladder cancer and agreed to be put in the study. The samples were stained with Immunohistochemistry Staining (IHC), and then we quantitatively counted the number of the Ki-67 stained nucleus on a microscope.RESULTS:A total of 54 samples were obtained in this study. Samples consisted of 27 samples with NMIBC and 27 samples with MIBC. The cut-off point was 20%, we found 17 patients with MIBC and 14 patients with NMIBC presented with biomarker > 20%. Biomarker ≤ 20% was found in 10 patients with MIBC and 13 patients with NMIBC. On statistical analysis with Chi-Square test, no significant association found (p = 0.583) between KI-67 and muscle - invasiveness with OR of 1.579, 95% CI (0.533-4.678).CONCLUSION:There is no association between expression of Ki-67 and muscle invasiveness in bladder cancer.
