Therefore, identification of different molecules and proteins involved in the regulation of these pathways may contribute to find new therapeutic targets. A member of the M28 family of the metallopeptidases, Endoplasmic Reticulum Metallo Protease 1 (ERMP1), is overexpressed in cancers such as colorectal cancer. The role of this protein in the UPR activation was previously reported in breast cancer. We aimed to evaluate the role of ERMP1 in the activation of autophagy and apoptosis in colorectal cancer.MethodsERMP1 Gene silencing was performed using specific small hairpin RNA (shRNA) in HCT-116 colorectal cancer cell line. Then, autophagy associated protein markers including Beclin 1, p62 and LC3II were evaluated using western blot. The effect of ERMP1 knockdown on cellular apoptosis was also assessed by propidium iodide staining flow cytometry analysis. Statistical analysis was performed using SPSS software version 20.ResultsAll three autophagy markers were increased significantly in the ERMP1-silenced HCT116 cell lines compared with negative control cells (P 0.05).ConclusionThe oncogenic protein, ERMP1, activates autophagy in colorectal cancer cell line. Targeting of ERMP1 may be considered as a proper approach in colorectal cancer therapy. Further investigations are required to confirm these results.","PeriodicalId":8370,"journal":{"name":"Annals of Colorectal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76903544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We performed the pre-stage ghost ileostomy (GI) without parietal wall split. The technique of GI is that after the completion of resection-anastomosis of rectal cancer, a terminal ileal loop at about 20cm from ileocecal junction is identified. Small (10-12F) Ryle’s tube (RT) is passed through a small opening in the mesentery of the identified ileal loop. A small 4-5mm incision is given on abdominal wall at pre-operatively marked proposed stoma site in right iliac fossa region. Haemostatic Kelly’s forceps is introduced through this small incision to get out the two limbs of the RT that has been already looped around the identified ileal loop. These two limbs of the RT are cut short and fixed to each other and to the skin around it with 2-0 silk sutures, taking care to keep the tubing loop loose enough to avoid any tension to the vascular supply of the ileal loop and without causing any luminal compression of the loop to avoid bowel obstruction. In case of AL, the pre-stage GI can be converted into a formal covering stoma under local or spinal anesthesia by gentle pull of the two limbs of the looped RT to extract the isolated ileal loop through an adequate circular incision around the site of GI. In case of uncomplicated postoperative course, the fixing RT is pulled out gently from the abdominal cavity to release down the GI.","PeriodicalId":8370,"journal":{"name":"Annals of Colorectal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78840789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lifetime risk of colorectal cancer (CRC) in patients with CF is approximately 5-10 times that of the general population. In 2018, the CF Foundation CRC Screening Task Force recommended initiating CRC screening in adults with CF at age 40. Case Presentations In this case series, we present three cases of females with CF younger than age 40 diagnosed with CRC with variable presentations and stages. We discuss the data supporting current CRC screening guidelines in CF in an effort to raise awareness among clinicians regarding young-onset CRC in this population. Furthermore, we aim for this case series to help drive further investigation into the mechanisms underlying CF-related CRC and to open the door to changes in current screening practices. Conclusion People with CF are at substantially higher risk of development of CRC relative to the general population. While current CRC screening practices advocate for earlier screening in this population compared to average-risk patients, this case series highlights potential limitations to current screening guidelines.","PeriodicalId":8370,"journal":{"name":"Annals of Colorectal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77197921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this investigation was to evaluate the protective effect of gallic acid and pyrogallol in colorectal cancer. Previous reports suggest that there is an association present between some tannase producing bacteria and colorectal cancer. Tannase hydrolyze tannic acid into gallic acid and pyrogallol. Are those compounds have any therapeutic effect on colorectal cancer? This study will help to find those quarries. Methods-The remedial effect of gallic acid and pyrogallol was studied by descriptor properties and molecular docking methods. 100 CRC causing protein structures were docked in this investigation. Results- Lipinski Rule of Five and other descriptor properties of those compounds have showed their nontoxic and therapeutic nature. Molecular docking studies have showed highest score -38.22 KJ/Mol with gallic acid and -33.6 KJ/Mol with pyrogallol. Conclusion- This is the first report on docking investigation of these large numbers of protein. The findings of this research concluded that gallic acid and pyrogallol have a protective effect in colorectal cancer by stopping the effect of those CRC causing protein.","PeriodicalId":8370,"journal":{"name":"Annals of Colorectal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78307583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diagnosis and treatment of these cases in emergency departments may be difficult. The effective use of radiological imaging techniques can accelerate and facilitate this process. Case presentation: A 65-year-old male patient, who underwent computed tomography with the suspicion of a foreign body in the rectum, was admitted to the emergency outpatient clinic. The patient was a male patient with a psychiatric illness who later underwent emergency surgery. Since the patient had impaired consciousness during the examination, anamnesis could not be obtained, so surgical consultation in the emergency service was first consulted as perforation due to rectal tumoral thickening. In almost all cases, plain radiography is sufficient and can eliminate diagnostic difficulties. However, this is not possible in non-opaque objects. Therefore, CT played an important role in the diagnosis of this patient. A 30cm foreign body, salami, was removed from the abdomen of the patient, who was later taken into emergency surgery. Conlusion: The guiding role of radiological examinations in diagnosis and treatment was discussed, and it was emphasized that CT is a problem-solving tool for rectal foreign body.","PeriodicalId":8370,"journal":{"name":"Annals of Colorectal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82139323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

METHODS: A set of clinical criteria based on physical findings was used to diagnose patients with simple anal fistula. These patients were operated under local anesthesia with conscious sedation. Intravenous paracetamol, diclofenac sodium, and midazolam were administered as adjuvants. Fistulotomy with/without marsupialisation was performed in most patients. Clinical diagnosis was matched with operative findings. RESULTS: Among 193 patients presenting with anal fistula, 61 patients were diagnosed as simple anal fistula and were scheduled for surgery under local anesthesia with conscious sedation. One patient was found to have complex anal fistula during intraoperative assessment and surgery was deferred. Surgery could be completed under local anesthesia with conscious sedation for 58/60 (96.7%) patients. Acceptability of the procedure was assessed with two parameters: the patients’ satisfaction score on visual analogue scale and their willingness to undergo fistula surgery under local anesthesia again, if required. Median (interquartile range) visual analogue scale score for patients’ satisfaction was 10 (9-10). All the patients expressed their willingness to undergo fistula surgery under local anesthesia again, if required. The clinical criteria was successful in diagnosing simple anal fistula in 58/61 (95.1%) patients. The remaining three patients had high intersphincteric fistula (1) and blind sinus (2). CONCLUSIONS: Acceptability of surgery for simple anal fistula under local anesthesia with conscious sedation was excellent. The proposed clinical criteria were highly accurate in diagnosing simple anal fistula.","PeriodicalId":8370,"journal":{"name":"Annals of Colorectal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76850224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There have been fewer reports of sigmoid volvulus in Thailand. The aims of this study were to assess characteristics and outcomes of treatment in patients who were diagnosed with sigmoid volvulus at Maharat Nakhon Ratchasima Hospital over a 10-year period. Methods: This retrospective study included 42 sigmoid volvulus patients between 01/2010 and 12/2019. Patients’ characteristics, investigations for diagnosis, operative details and postoperative outcomes were analyzed. Results: From 42 sigmoid volvulus patients, 34 (80%) were males with average age of 64.6 years. Two most common co-morbidities were hypertension (33.3%) and bedridden status (14.2%). Classic “Coffee bean” sign on plain abdominal radiography was found in 33 patients (78.6%). Colonoscopic detorsion was attempted in 17 patients (40.5%) with a success rate of 76.5%. From 13 patients who had successful detorsion, only 5 patients (38.5%) underwent sigmoidectomy with primary anastomosis in the same index admission. Overall 30-day mortality rate was 9.5% and mortality rate was 10.3% for emergency surgery. Conclusions: Sigmoid volvulus usually presents in elderly patients. Endoscopic detorsion should be the initial management of patients without peritonitis. Sigmoidectomy should be done in the same index admission.","PeriodicalId":8370,"journal":{"name":"Annals of Colorectal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81928471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
