BACKGROUND The goal of the present work was to assess the antibacterial activity of nano-magnesium hydroxide (NMH) against Streptococcus mutans (S. mutans) and to explore the antimicrobial function of AH Plus™ sealer incorporating NMH. MATERIAL AND METHODS The antimicrobial behavior of NMH against S. mutans was evaluated with bactericidal tests. A modified direct contact test was used to assess the antimicrobial activity of unset AH Plus containing NMH after 5 minutes, 20 minutes, and 60 minutes of contact with bacteria. The antimicrobial effects and the amount of surface-adhering bacteria of the solidified materials were explored by SEM and confocal laser scanning microscopy, respectively. RESULTS NMH powder presented excellent antimicrobial activity against S. mutans. Mg²⁺ and OH⁻ were not the main factors resulting in bacterial death. Approximately 93.1% and 98% of the S. mutans were killed in the AH Plus+7% NMH group after incubation for 5 minutes and 20 minutes, respectively. AH Plus with 5% or 7% NMH were more potent against S. mutans compared with AH Plus alone (P less then 0.05). Moreover, the antibacterial function of AH Plus was lost after setting. NMH enabled the solidified AH Plus to still have antibacterial properties on the seventh day. CONCLUSIONS NMH can be used to modify AH Plus sealer to eradicate residual bacteria and prevent reinfection.Spontaneous splenic rupture is a rare entity that requires high index of suspicion for diagnosis. Usually, it occurs due to underlying pathology that could be inflammatory, neoplastic or infectious. However, there are also cases of spontaneous splenic rupture in a normal-sized spleen without obvious pathologic process. In our case, the patient suffered a spontaneous splenic rupture 1 week after laparoscopic appendectomy due to acute appendicitis. Histopathologic examination revealed a normal-sized spleen without any obvious pathology. In our patient, we did not found any explanation for a spontaneous splenic rupture, besides her primary inflammatory condition.These are recommendations from the Indian Association of Gastro Intestinal Endo Surgeons for safe performance of diagnostic and therapeutic endoscopy during the COVID-19 pandemic.These are inter-society guidelines for performance of laparoscopic surgery during COVID-19 pandemic that has affected the way of surgical practice. The safety of healthcare workers and patients is being challenged. It is prudent that our surgical practice should adapt to this rapidly changing health environment. The guidance issued is based on global practices and national governmental directives. The Inter-Society Group urges you to be updated with the developing situation and evolving changes.Here, we developed a prostate cancer (PCa) risk nomogram including lymphocyte-to-monocyte ratio (LMR) for initial prostate biopsy, and internal and external validation were further conducted. A prediction model was developed on a training set. Significant risk factors with P 4% and less then 99%. The nomogram predicting PCa risk in patients with PSA 4-10 ng ml-1 also displayed good calibration and discrimination performance (C-index 0.734, 95% CI 0.708-0.760). This nomogram incorporating age, PSA, digital rectal examination, abnormal imaging signals, PSA density, and LMR could be used to facilitate individual PCa risk prediction in initial prostate biopsy.This retrospective study analyzed the level of concordance between clinical and autopsy diagnosis of coarctation of aorta over 10 years. Utilizing the Goldmann classification, the concordance rate was found to be 16%. Major discrepancies (Class I and II) were found in 56% cases and minor discrepancies (Class III and IV) in 28% cases.Aim In this study, we aimed to determine the clinical value and prognostic significance of the Neutrophil / Lymphocyte Ratio in patients undergoing curative surgery due to esophageal cancer. Material and method Patients who underwent curative resection for esophageal cancer between 2015-2019 were included in the study. Two groups, Group1 (low NLR) and Group2 (high NLR), were created. Demographic and clinical features, intraoperative and postoperative results, tumor characteristics and mean survival were compared in the groups. Results A total of 48 patients participated in our study. Group 1 consisted of 18 patients and Group 2 consisted of 30 patients. Male sex was dominant in both groups (66.7% vs 73.3%, p. 0.431). Preoperative CEA was higher in Group 2 (3.97 vs 9.57, p. check details 0.032). Tumor diameter was larger in Group2 (3.33 vs 5.40 cm, p. 0.000). Adenocarcinoma was higher in Group 2 (33% vs 53.3%, p. 0.047), while squamous cell carcinoma was higher in Group 1 (66.7% vs 33.3%, p. 0.047). Lymph node positivity was higher in Group 2 (66.7% vs 93.3%, p. 0.024). The anastomosis leak was higher in Group 2 (0% vs 20%, p. 0.048). Postoperative hospital stay was longer in Group 2 (13.27 vs 23.9 days, p. 0.009). 90-day readmission was higher in Group1 (33.3% vs 3.3%, p. 0.008). Survival duration was shorter in Group 2 (29 vs 15 months, p. 0.005). Conclusion This study revealed that preoperative high NLR was associated with poor survival, along with greater tumor diameter, increased lymph node metastasis rate, and increased anastomosis leakage in patients with esophageal cancer. These results suggest that modifying inflammatory responses and modulating the immune system may improve survival outcomes in patients with esophageal cancer.

While debate on prophylactic resection of incidental Meckel's diverticulum continues, there have been reports of its successful use for urinary diversion and reconstruction. In contrast, its use as a means of fecal diversion has been described anecdotally. Herein, we describe our technique of temporary fecal diversion using Meckel's diverticulum as reliable conduit for stoma formation in a toddler. The stoma functioned well until continuity of bowel was restored and diverticulum resected safely. We trust that our limited experience will encourage other colleagues to test the inventive use of Meckel's diverticulum as a potentially safe and effective option to fit in the surgical armamentarium for temporary fecal diversion.

We emphasized that the patient had undergone surgery 4 years before for a rectal adenocarcinoma, in which we performed an abdominal perineal resection of the rectum with end colostomy. link2 At the time of admission, there were no imagistic signs of local or distant relapse. The surgical technique used aimed to repair both of the abdominal defects by placing a large polypropylene mesh (30x30 cm) spanning into the retro-rectus space in a sublay position. On the colostomy side, the mesh is extended up to the median axillary line by performing TAR (transversus abdominis release), according to the technique described by Pauli, thus the colostomy side is not modified. The post-operatory evolution was favourable, with the return of intestinal transit for faeces and gas on the second post-operatory day. The patient was discharged on the 7th postoperatory day, after the suppression of the over-prosthetic drainage. Key words Parastomal hernia, PCS/TAR.Introduction Sinistroposition of the gallbladder, or true left-sided gallbladder (LSG) without situs viscerum inversus, is a rare congenital anatomical variant where the gallbladder is located to the left of round/falciform ligament. It can be associated with anomalies of the biliary tree, portal system and hepatic vascularization. The surgical management of a LSG could be challenging even for an experienced operator, being usually an incidental intraoperative finding. Case report A 72 years old woman was admitted to our emergency department because of acute cholecystitis. There were no pre-operative indications of sinistroposition of the gallbladder and its aberrant position was discovered during the explorative laparoscopy; because of the unusual anatomy and chronic flogosis, the laparoscopic approach was converted to open surgery. The patient underwent a successful intervention and was discharged after 4 days without complications. link3 Her family history revealed a daughter with biliary atresia. Discussion LSG could remain undetected at preoperative imaging, but today, with advances in diagnostic imaging, the report of this condition has increased. Several hypothesis suggest the presence of an underlying embriologic mechanism for LSG and its associated anomalies, but its etiology is still unknown. The association with the daughter's biliary atresia makes reasonable a possible genetic correlation with this condition. Conclusions In case of LSG, laparoscopic cholecystectomy could be feasible and safe, but with an increased risk of injury to the major biliary structures, mostly in case of severe and chronic inflammation of the gallbladder. Surgeons have to know this variant because of its associated hepatic anomalies.

Pharmacodynamics describes a drug's impact on the body while pharmacokinetics describes the body's impact on a drug. Another way of understanding these terms is that pharmacodynamics is a description of both the positive and negative consequences of drugs attaining certain concentrations in the body while pharmacokinetics is concerned with our ability to reach and then sustain those concentrations. Unlike the drugs for which these concepts were developed, including antibiotics, the bacteriophages (or 'phages') that we consider here are not chemotherapeutics but instead are the viruses of bacteria. Here we review the pharmacology of these viruses, particularly as they can be employed to combat bacterial infections (phage therapy). Overall, an improved pharmacological understanding of phage therapy should allow for more informed development of phages as antibacterial 'drugs', allow for more rational post hoc debugging of phage therapy experiments, and encourage improved design of phage therapy protocols. Contrasting with antibiotics, however, phages as viruses impact individual bacterial cells as single virions rather than as swarms of molecules, and while they are killing bacteria, bacteriophages also can amplify phage numbers, in situ. Explorations of phage therapy pharmacology consequently can often be informed as well by basic principles of the ecological interactions between phages and bacteria as by study of the pharmacology of drugs. Bacteriophages in phage therapy thus can display somewhat unique as well as more traditional pharmacological aspects.Background Immune checkpoint blockade has emerged as a highly effective treatment for patients with metastatic melanoma and cutaneous squamous cell carcinoma. Nivolumab blocks the interactions between programmed cell death protein 1 and programmed death ligand 1 allowing for activation of a latent immune response against the malignancy. Ipilimumab binds to and blocks cytotoxic T-lymphocyte-associated protein 4, alleviating the negative regulation of T-cell activation that is mediated by that checkpoint. Combination therapy with nivolumab and ipilimumab is associated with longer overall survival at 5 years compared with nivolumab monotherapy. Solid organ transplant recipients have a significantly higher risk of malignancies compared with the general population. There is limited data surrounding the efficacy of combination immunotherapy in solid organ transplant recipients, as these patients were excluded from seminal trials due to risk of organ rejection. Case presentations Here we present four cases of combination immunotherapy in kidney transplant recipients.
